US President Joe Biden and Prime Minister Benjamin Netanyahu are expected to speak soon, multiple officials familiar with the matter say. 

US national security adviser Jake Sullivan has been in touch with his Israeli counterpart about the situation in Israel, a senior Biden administration official says. Officials at the National Security Council at all levels are reaching out to their counterparts as well.

Meanwhile, here's what how some other nations are reacting:

UAE: The foreign ministry in a statement stressed the need to “stop escalation” between Palestinians and Israelis and “preserve human lives.” 

“The UAE calls for the exercise of maximum restraint and an immediate ceasefire to avoid dangerous repercussions,” the statement published on state-run WAM said. 

Spain: Foreign minister José Manuel Albares said Spain strongly condemns “the very serious terrorist attacks from Gaza against Israel” and said he is “overwhelmed by this indiscriminate violence.” 

“All our solidarity with the victims. Spain is firmly committed to peace, security and stability in the region,” he said in a post on X, formerly known at Twitter.

Italy: "The Italian government is closely following the brutal attack taking place in Israel. It condemns in the strongest terms the ongoing terror and violence against innocent civilians and supports Israel's right to defend itself. Terror will never prevail," the Italian presidency said.
