BEIRUT — The 57-member Organization of Islamic Cooperation held an emergency virtual meeting Sunday over the situation in Gaza calling for an end to Israel’s military attacks on the Gaza Strip.

Saudi Foreign Minister Prince Faisal bin Farhan urged the international community to work on ending Israel’s military operations against Gaza and to allow aid to reach the coastal region.

Speaking from Ramallah in the West Bank, Palestinian Foreign Minister Riad Malki blasted Israel calling it an “apartheid state” that is practicing “crimes and brutality against our people in Gaza.” He added that the latest round of violence that began on Monday has displaced 10,000 people.

“The rise of the Palestinian people has made it clear that Jerusalem is a red line,” Malki said. He added that “our people will not be exhausted by Israel’s killing machine.”

Malki said all of Israel’s attempts to make demographic changes in Sheik Jarrah neighborhood in Jerusalem will fail.

Malki urged Muslim countries to support the Palestinian people by all means urging them to impose political and economic sanctions against Israel.

JERUSALEM — Israeli airstrikes on Gaza City flattened three buildings and killed at least 23 people on Sunday, medics said, making it the deadliest single attack since heavy fighting broke out between Israel and the territory’s militant Hamas rulers nearly a week ago.

The Gaza Health Ministry said another 50 people were wounded in the attack. Rescuers were racing to pull survivors and bodies from the rubble.

Earlier, the Israeli military said it destroyed the home of Gaza’s top Hamas leader in a separate strike. It was the third such attack in the last two days.

Israel appears to have stepped up strikes in recent days to inflict as much damage as possible on Hamas as efforts to broker a cease-fire accelerate. A U.S. diplomat is in the region to try to de-escalate tensions, and the U.N. Security Council is set to meet Sunday.

The military said it struck the homes of Yehiyeh Sinwar, the most senior Hamas leader inside the territory, and his brother Muhammad, another senior Hamas member. On Saturday it destroyed the home of Khalil al-Hayeh, a senior figure in Hamas’ political branch.

Brig. Gen. Hidai Zilberman confirmed the strike on Sinwar’s house in the southern Gaza town of Khan Younis to army radio.

BERLIN — German Foreign Minister Heiko Maas said in comments to Sunday’s edition of the Bild am Sonntag newspaper that “Israel is using its right to self-defense to protect its population from Hamas’ rocket terror.”

He said there needs to be “1. An end to the rocket terror. 2. An end to the violence and 3. a return to talks on concrete confidence-building steps between Israelis and Palestinians and a two-state solution.”

A pair of tweets from his ministry Sunday expanding on those comments quoted Maas as saying that he has made that clear in his talks over recent days with counterparts in the region. He voiced concern about “the reports about ongoing violence, and people’s fear and desperation. This is an explosive mixture that could lead to unpredictable consequences, including for the region overall. We must prevent this happening.”

There has been no specific German government comment so far about Saturday’s Israeli strike that destroyed the high-rise building in Gaza that housed the offices of The Associated Press and other media.

GAZA CITY, Gaza Strip — Israeli warplanes have struck several buildings and roads in a vital part of Gaza City early Sunday.

According to photos circulated by residents and journalists, the airstrikes created a crater that blocked one of the main roads leading to Shifa, the largest hospital in the strip.

The Health Ministry said the latest airstrikes left at least two dead and 25 wounded, including children and women. It said rescuers are still digging through the rubble and had so far pulled up five more wounded.

Two hours into the heavy bombardment, there has been no comment from the Israeli military.

BEIJING — Chinese Foreign Minister Wang Yi has called on the U.N. Security Council to seek an early de-escalation of violence between Israel and Gaza’s Hamas rulers. He also blamed the U.S. for the council’s lack of action so far.

“Regrettably, the council has so far failed to reach an agreement, with the United States standing on the opposite side of international justice,” the state-run Xinhua News Agency quoted Wang as saying in a phone conversation Saturday with Pakistani Foreign Minister Shah Mahmood Qureshi.

He expressed support for a two-state solution, and said China, which holds the Security Council presidency this month, expects all parties to speak with a unified voice when the council discusses the conflict later Sunday.

Wang said the Security Council should reconfirm a two-state solution and urge Palestinians and Israelis to resume talks on that basis as soon as possible.

UNITED NATIONS -- A U.N. spokesman says Secretary-General Antonio Guterres is “deeply disturbed” by the Israeli airstrike that destroyed a high-rise building in Gaza City housing offices of several international media organizations and residential apartments, and is “dismayed” by the increasing number of civilian casualties.

“The secretary-general reminds all sides that any indiscriminate targeting of civilian and media structures violates international law and must be avoided at all costs,” spokesman Stephane Dujarric said Saturday.

Earlier Saturday, an Israeli airstrike pulverized a high-rise building that housed The Associated Press, Al Jazeera and other media after warning that it was being targeted.

Guterres singled out the death of 10 members of the same family including children as a result of an Israeli airstrike Friday in the al-Shati refugee camp in Gaza, spokesman Stephane Dujarric said Saturday.

LOS ANGELES — Hundreds of protesters shut down traffic as they took to the streets of Los Angeles, calling for an end to Israeli airstrikes over the Gaza Strip.

The protesters waved flags and signs that said “free Palestine” and shouted “long live intifada,” or uprising. They marched from outside the federal building to the Israeli Consulate in the western part of the city on Saturday.

Police shut down traffic on Wilshire Boulevard, a major thoroughfare, and urged motorists to avoid the area. Police from multiple agencies were monitoring the ongoing demonstration.

Also on Saturday, hundreds of protesters gathered in Boston’s Copley Square and walked a short distance through the streets to the location of the Israeli Consulate for New England, blocking traffic.

Footage on social media shows protesters then unfurled a banner in the colors of the Palestinian flag with the words “Free Palestine” while standing on top of the awning of the building where the consulate is located.

Other smaller protests in support of Palestinians took place in Hartford and Pittsburgh.

JERUSALEM — Israeli Prime Minister Benjamin Netanyahu says the ongoing campaign against Palestinian militants, now in its sixth day, will “continue as long as needed.”

The prime minister spoke on Saturday from Israel’s defense ministry headquarters in Tel Aviv and issued a warning to leaders of Gaza's militant Hamas group after a series of airstrikes targeted high-level officials and commanders.

Netanyahu says: “You cannot hide — not above ground, and not underground. Nobody is immune.”

The Israeli leader added that there was “no more just or moral campaign” than Israel’s against Hamas in the Gaza Strip, and thanked President Joe Biden and other world leaders for their support.

Netanyahu's remarks came at the end of a day that saw Israeli airstrikes target and destroy a high-rise building in Gaza City that housed offices of The Associated Press and other media outlets. Everyone was safely evacuated from the building before the strike hit.

JERUSALEM — Israel’s Electric Company says that high voltage lines supplying the Gaza Strip with electricity were damaged by rocket fire by Palestinian militants.

The company released a statement on Saturday saying five of the 10 lines have been damaged, in the latest escalation of fighting and that the company cannot fix them because there is no access to the area.

Damage to the power lines came amid days of intense fighting between Palestinian militants and Israel in the Gaza Strip.

Gaza's only other source of electricity — besides the power provided by Israel — is its single power plant, which has been working only partially due to fuel shortages. However, both sources are insufficient to cover Gazans' needs.

Outages of at least eight hours have long been a daily occurrence in the strip and with the power plant not working at regular capacity, rolling blackouts have increased to 12-15 hours per day recently.

With the latest hits on the power line, more outages are expected.

BEIRUT — A top Hamas leader says militant groups in the Gaza Strip will not retreat in the face of attacks by Israeli troops, warning that their fighters still haven’t used all their force at their disposal.

Ismail Haniyeh spoke during a rally attended by hundreds in the gas-rich nation of Qatar on Saturday night. He said that “resistance is the shortest road to Jerusalem” and that Palestinians will not accept anything less than a Palestinian state with Jerusalem as its capital.

He added that “the Zionist enemy struck Gaza, flattened towers and carried out massacres,” thinking that this will make militant groups retreat. He said that as the Israeli attacks escalate, “the resistance will increase (its force) to a higher level.”

Haniyeh also said that despite the fact that Gaza has been under siege for nearly 15 years, militant groups will not retreat.

WASHINGTON — President Joe Biden has expressed “strong support” for Israel’s strikes in Gaza in retaliation for Hamas missile attacks on its territory, but raised concerns about civilian casualties and the protection of journalists on a call with Israeli Prime Minister Benjamin Netanyahu.

The White House says Biden on Saturday also shared his “grave concern” about intercommunal violence within Israel and escalating tensions in the West Bank. Biden and Netanyahu also discussed Jerusalem, with Biden saying it should “be a place of peaceful coexistence for people of all faiths and backgrounds.”

Biden also held his first call since taking office with Palestinian Authority President Mahmoud Abbas to discuss the violence, in which he called for Hamas, the PA’s rival, to stop firing rockets into Israel.

The White House says Biden “expressed his support for steps to enable the Palestinian people to enjoy the dignity, security, freedom, and economic opportunity that they deserve” and highlighted the resumption of U.S. aid to the Palestinians under his administration.

RAMALLAH, West Bank — Palestinian President Mahmoud Abbas has spoken on the phone with President Joe Biden and urged the U.S. to intervene in the conflict and “put an end to Israeli attacks on Palestinians.”

The official Palestinian news agency Wafa says Abbas on Saturday updated Biden on the escalations across the Palestinian territories and said he was working to halt “the Israeli aggression against our people and to reach a cease-fire.”

The report says Abbas also told Biden that “security and stability will be achieved when the Israeli occupation ends,” adding that Palestinians are ready and willing to work toward peace with international mediators.

Biden stressed the need to achieve calm and reduce violence in the Mideast, noting intensive American diplomatic efforts to that end. That's according to the Wafa statement.
