Israel’s military has pledged to step up its bombardment of the besieged Gaza Strip in the next stage of the war, vowing to continue to attack targets that could be considered a threat to its ground forces.

Israel is widely expected to launch a major ground offensive into Gaza to “demolish” the Palestinian militant group Hamas.

Palestinians say they have received new warnings from Israel’s military to move from north Gaza to the south, Reuters reported, with the added warning they may be identified as sympathizers with a “terrorist organization” if they stay put.

Meanwhile, Israel’s military launched an air strike on an underground compound at a mosque in the occupied West Bank that allegedly contained a “terror cell.”

Global aid organizations warned that humanitarian relief that has trickled into the Gaza Strip is “far from enough” and “totally insufficient.” The U.N. has called for “unrestricted humanitarian access throughout Gaza” and warned that health facilities could run out of fuel “in the next day or so.”

Early Sunday, Egyptian media reported that a second convoy of 17 trucks crossed into Gaza, but the reports proved to be inaccurate. Later Sunday, 14 humanitarian aid trucks did cross into Gaza and Cindy McCain, the director of the United Nations World Food Programme, said 40 more are expected tomorrow. On Saturday, the first 20-truck convoy carrying food, water and medicine entered the besieged Palestinian enclave for the first time since the start of the war.

The U.S. will be deploying more military assets to the Middle East to bolster regional deterrence efforts amid escalating tensions by Iran and its proxy forces across the region, the U.S. Defense Secretary said.

It is over two weeks since the Palestinian militant group Hamas launched its assault on Israel, killing 1,400 people and taking 200 hostage. Over 4,300 people have been killed in Gaza and more than 13,500 injured since the Israel-Hamas war began, according to Palestinian authorities.

In the wake of the deadly terrorist attack on Israel earlier this month and the country’s response to it, protestors and bigots have taken to social media to spout hateful rhetoric about Israelis. Now, many American Jews who feel unsafe are putting aside their distaste for guns and gun ownership and are buying weapons to protect themselves, according to an NBC News report.

There has been a rush of new customers seeking to buy guns and train up how to use them, according to NBC News.

“We’ve definitely seen a tremendous increase in religious Jewish people, Orthodox people, purchasing firearms,” David Kowalsky, owner of Florida Gun Store in Hollywood, who also offers firearms training, told NBC News. “I’ve seen a surge in interest in individual training as well as group training.”
