At least 30 US citizens have died in Israel, a State Department official said Sunday.
That number has risen by one since Saturday.
The State Department is "also aware of 13 American nationals who are unaccounted-for,” the spokesperson said. That number has gone down by two people since Saturday.
The spokesperson said officials have been in contact with families, and that the US government "is working around the clock to determine their whereabouts."
Americans are believed to be among the hostages taken by Hamas when it launched its October 7 surprise attack on Israel.
The US "is working with the Israeli government on every aspect of the hostage crisis," the spokesperson said, "including sharing intelligence and deploying experts from across the United States government to advise the Israeli government on hostage recovery efforts."
