U.S. Secretary of State Marco Rubio on Friday toured a U.S.-led center in Israel overseeing the Gaza ceasefire, as the Trump administration worked to set up an international security force in the territory and shore up the tenuous truce between Israel and Hamas.

Gaza’s fragile ceasefire faced its first major test Sunday as Israeli forces launched a wave of deadly strikes, saying Hamas militants had killed two soldiers.

Vice President JD Vance said a Knesset vote was an "insult." Secretary of State Marco Rubio planned to meet with Israeli Prime Minister Benjamin Netanyahu later Thursday.

Vice President JD Vance visits the Church of the Holy Sepulchre during his trip to Israel, calling it an "amazing blessing" and a "very special moment."

Several top U.S. officials are in Israel to shore up the Gaza ceasefire and attempt to bring about a permanent end to the war. They acknowledge the next phase poses serious challenges.

Lebanon’s president Thursday met with the recently-appointed U.S. general heading a committee monitoring the fragile ceasefire between Israel and the Hezbollah militant group.

The vice president said that while he can't have "100% certainty that it's going to work," he has "great optimism the ceasefire is going to hold."
