The mother of Israeli-American hostage Edan Alexander says she has been assured by Prime Minister Benjamin Netanyahu that “conditions are ripe” for a hostage deal, just hours after Hamas released a video of her son begging the Israeli leader and US President-elect Donald Trump for his release.

Hamas released a video on Saturday with proof of life from U.S. citizen Idan Alexander, who is being held hostage in Gaza — and in the footage, he calls on President-elect Trump to negotiate for his release.

The Israeli prime minister's office released a statement saying that Netanyahu had "promised that Israel is determined to take every action to bring them back home, together with all of the hostages held by the enemy".

New Jersey native Idan Alexander was featured in an eerie video posted by Hamas Saturday that suggested the days might be numbered for him and other remaining hostages taken by the terror group.
