“Fighting is escalating in Khan Younis — the UNRWA Training Centre sheltering 10Ks of displaced people has just been hit — buildings ablaze and mass casualties — safe access to/from the centre has been denied for 2 days — people are trapped,” White posted on X Wednesday.

U.S. National Security Council spokesman John Kirby on Wednesday said he didn’t have enough initial info to comment on the reported attacks. But he said Israel is transiting its military operations against Hamas while undertaking more-targeted operations.

“Low-intensity operations doesn’t mean no-intensity operations,” Kirby said at a White House press briefing on Wednesday.

“They have removed a division of troops,” Kirby said. “That’s a lot of troops. That’s thousands of troops. And they are pursuing, on the ground, more targeted operations against – particularly against the leadership. They are relying less on … on airstrikes.”

The IDF said its military action was intended to eliminate terrorist cells operating in Gaza and include infantry, as well as armored and aerial forces.

Regarding those actions, the IDF posted on X that its operations affected “numerous” militant strongholds.

“Troops have eliminated numerous terrorist cells with sniper, tank and aerial fire, including on cell planning to carry out anti-tank fire on forces. Troops also conducted targeted operational activities in the area, locating weapons, engaging in combat and eliminating terrorists.”

Israel’s military operations in Gaza on Wednesday included eliminating an “armed enemy observer” planning to fire upon Israeli forces in central Gaza and eliminating “numerous terrorists” with aerial attacks in northern Gaza, the IDF posted on X.

The ongoing Israeli military actions in Gaza are in response to the Oct. 7 Hamas attack on Israel that killed an estimated 1,200 people.

Hamas militants kidnapped about 250 people during the initial attack, including some who were citizens of the United States. Hamas since has released 110 hostages and said many others have died.
