Israel-Gaza live updates: Netanyahu seeks pardon over corruption charges

The Red Cross is on its way to receive the coffin of a newly found Israeli hostage from Hamas in Gaza, according to a joint statement issued Tuesday by the Israeli military and the Israeli Security Agency. Hamas announced earlier that it would hand over the remains, which it claims belong to an Israeli hostage, at 4 p.m. local time / 9 a.m. ET.

The remains of three hostages are still in Gaza.

Israeli Prime Minister Benjamin Netanyahu on Tuesday accused Palestinian Islamic Jihad -- one of the main Palestinian armed factions operating in Gaza -- of violating the ceasefire by delaying the return of a deceased hostage's body.

"Israel views with utmost seriousness the delay in their immediate transfer to its hands," Netanyahu said of the remains reportedly discovered in Gaza on Monday.

"Israel demands the immediate return of the three deceased hostages still held in the Gaza Strip," the prime minister said in a statement published to social media by his office.

The Israel Defense Forces said “several terrorists” crossed the yellow line that separates the part of Gaza controlled by Israeli troops from the part of Gaza where Israeli troops withdrew from during the ceasefire agreement.

People were identified crossing the yellow line in Khan Younis and in northern Gaza, the IDF said in separate statements. Five people were targeted by Israeli troops in these incidents and at least two people were killed, the IDF said.

Israeli forces chose to carry out the strike in Lebanon that killed Hezbollah chief of staff Haitham Ali Tabataba'I on Sunday as a “contained, opportunity-based elimination,” an Israeli military official said Monday.

Israel “chose to carry out the strike now after identifying a clear window of opportunity to target a key terrorist in the organization,” the official said. “There is no intention to escalate. This is a contained, opportunity-based elimination.”

Israeli forces have been striking targets in southern Lebanon they say are associated with Hezbollah in October and November since the Israel-Hamas ceasefre went into effect. This is the first time Israel has struck Beirut, Lebanon’s capital, since June.
