The U.S. State Department is in touch with three Americans who were detained by Israel last month, agency spokesman Matthew Miller said.

Last week, embassy officials met with Samaher Esmail, a U.S. citizen being held in the occupied West Bank, over allegations of “incitement on social media.”

Officials also met today with Borak Alagha, 18, and Hashem Alagha, 20, two brothers born in the Chicago area, who were detained by Israeli forces.

Miller couldn’t provide any details about the individual cases, adding that the State Department is only in the beginning stages of gathering information to determine whether they were wrongfully detained.

“I don’t have any assessment to offer about their case other than that is true for all Americans in Israel or anywhere around the world: Their safety and security is our first priority,” Miller said.

President Joe Biden said today that he is hopeful that a cease-fire will be announced in the coming days. “We’re close,” he said.

“My national security adviser tells me we’re close. We’re close. It’s not done yet,” Biden said during a stop in New York City to get ice cream. “And my hope is by next Monday we’ll have a cease-fire.”

Israeli Defense Minister Yoav Gallant said earlier today that even if there were a temporary cease-fire, “we will then continue fighting until the very last hostages return.”
