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.

Hamas posted an eerie video Saturday featuring New Jersey native Idan Alexander that suggests the days might be numbered for him and the other remaining hostages captured by the terror group more than a year ago.

France said on Wednesday it believed Israeli Prime Minister Benjamin Netanyahu had immunity to actions by the International Criminal Court which is seeking his arrest for alleged war crimes in Gaza, given Israel has not signed up to the court statutes.

Israel's prime minister and former defence minister strongly deny allegations of war crimes in Gaza.

The warrant was issued to Netanyahu, his former defense minister Gallant, and Hamas officials, accusing them of war crimes.
