Israeli Prime Minister Benjamin Netanyahu sent a message to the residents of Gaza, calling for action to free the detainees in the Strip, while threatening a "grim fate."

"I appeal to the residents of Gaza. You can choose life and ensuring your future and the future of your families, or you can cling to destruction and death. The decision is yours. Choose life," Netanyahu said at the weekly cabinet meeting on Sunday.

Netanyahu was speaking, according to the Times of Israel, about the fate of dozens of detainees held by Hamas inside the Gaza Strip.

"We are committed to doing everything we can to bring back all the hostages. We are trying to exhaust every opportunity and every crack. I will not go into detail about it," he said.

Netanyahu reiterated his offer of $5 million to anyone who frees a captive alive.

He also said that Tel Aviv was checking a Hamas video on Saturday showing the body of a detainee the movement said it killed in an Israeli airstrike in the northern Gaza Strip. Netanyahu said he had spoken to the detainee's mother.

It is believed that there are about 100 "Israeli" detainees in the Gaza Strip now, only about half of whom are alive, according to the occupation's estimates.
