US President Donald Trump said on Saturday that Hamas failed to release all the hostages by 12 p.m., a deadline he imposed after the terror group threatened to not release any hostages, and the US "will back" whatever decision Israel makes in response.

It’s only three weeks into a fragile ceasefire, and Israel and Hamas are each ratcheting up allegations that the other party has violated the deal.

Palestinian militants released three Israeli hostages on Saturday in exchange for hundreds of Palestinian inmates freed by Israel, completing the latest swap despite fears the Gaza truce deal was near collapse.
