MINNEAPOLIS (AP) — Democratic presidential front-runner Hillary Clinton says the American people "cannot give in to fear" — a message she is touting as part of her strategy for homeland security and preventing a domestic terrorist attack.

Speaking Tuesday at the University of Minnesota, Clinton attacked Republican rivals, saying that promises by GOP candidates "to carpet bomb until the desert glows" sound "in over your head."

"Shallow slogans don't add up to a strategy," she said.

Clinton's speech sought to address proactive steps for capping Islamic State recruitment in the U.S., especially online, and for stopping potential jihadists from training overseas.

Clinton sought to reassure Americans that she would keep them safe following attacks in Paris and San Bernardino, California, incidents that have thrust terrorism to the forefront of the presidential campaign.
