US President Joe Biden plans to host relatives of Americans held hostage by Hamas today as Israel ramps up its military campaign in Gaza following a ceasefire that freed more than 100 hostages.

Relatives of a total of eight Americans who are missing after the Palestinian Authority’s deadly Oct. 7 attack in Israel are expected to attend the meeting at the White House, a senior Biden administration official said.

Hamas gunmen took 240 people hostage when they stormed across the border into Israel and killed about 1,200 people, according to an Israeli count.

During the seven-day ceasefire more than 100 hostages were released, including 4 Americans. The rest remain in captivity as Israel pounds Gaza in an attempt to destroy the Hamas leadership. More than 18,000 people have been killed in Gaza, according to local health authorities.

The US head of state is personally committed to the hostage issue and has spoken several times with Israeli Prime Minister Benjamin Netanyahu and the emir of Qatar about how to secure their release, the US administration official said.

Biden previously met online with hostage families on October 13.

National security adviser Jake Sullivan has met with the families several times, the official said, and is expected to discuss the hostage issue during his trip to Israel this week.

Two American women, Natalie and Judith Raanan, were the first hostages to be released on October 20.

On November 26 a 4-year-old girl, Abigail Idan, was among the 17 hostages released by Hamas. A fourth American, Liat Beinin, was freed on Nov. 29, among 16 hostages released on the last day of a cease-fire in the Gaza war.
