A senior Hamas official has stressed the group is willing to hand over all remaining hostages in Gaza if their repeated conditions are met.

Speaking on Sky News UK, Basem Naim said Hamas is ready to release the hostages "immediately if we can be sure that this will lead to an end of this war and first and foremost to allow the humanitarian aid to get into Gaza".

Separately, Naim spoke of US President Donald Trump's work in the region from Ukraine to Syria and Yemen.

"I think President Trump has the capability and the will to reach this peaceful situation," Naim said

The father of an Israeli soldier killed during the Hamas attack on Israel on October 7 called on the international community to act to free the hostages held in Gaza and for Hamas to return his son's remains.

Ruby Chen's son, Itay Chen, was serving as a soldier when Hamas carried out its surprise cross-border assault through southern Israeli towns and military bases, sparking the war in Gaza.

The dual US citizen was believed to be have been held hostage, but the Israeli military confirmed Itay's death in March of last year.

"My family was notified by the IDF that Itay most likely did not survive the October 7th attack. But for over 19 months, Hamas have not been willing to acknowledge, A, that he is in their possession and, B, what is his physical status," Chen told the Security Council on Thursday (May 15).

"Who denies the deceased the last basic human dignity that they deserve?

"What my family has been subjected to, this deliberate withholding of information about our son's fate, the refusal to return him back to us, the silence, that long silence, has been a form of slow, enduring psychological torture," he added.

Chen was addressing a U.N. Security Council briefing on the implementation of resolution 2474 concerning missing persons in armed conflict.
