Thousands of activists from around the world are expected to descend on Egypt on Thursday for a “Global March to Gaza,” a movement aiming to break the Israeli blockade that has pushed the territory to the brink of famine.

The United Nations General Assembly on Thursday overwhelmingly demanded an immediate, unconditional and permanent ceasefire in the war in Gaza and aid access, after the United States vetoed a similar effort in the Security Council last week.

Their boat was intercepted on Monday as they attempted to break Israel's naval blockade on Gaza and deliver a symbolic amount of aid.

Six more activists from the Freedom Flotilla Gaza humanitarian aid mission aboard the Madleen boat were deported from Israel Thursday. They had sought to deliver aid to Gaza but were stopped by Israel's naval blockade.

Yair Yaakov was kidnapped by Islamic Jihad in the Oct. 7, 2023, attacks on Israel, Prime Minister Benjamin Netanyahu said. The other hostage will be named later, the Israeli military said.

The arrests in Egypt follow Israel's interception of a boat carrying activists on their way to Gaza, including environmental campaigner Greta Thunberg. Egypt has cracked down on pro-Palestinian activists even as it publicly condemns Israeli aid restrictions and has called for an end to the war.
