Disturbing video evidence has surfaced showing Hamas terrorists executing seven Palestinian men accused of collaboration, leaving the recently announced Gaza ceasefire in serious doubt.

The footage shows kneeling victims with hands restrained behind their backs before armed fighters open fire, while onlookers celebrate and record the killings on mobile phones.

The executions emerged just hours after the Donald Trump-mediated peace agreement, which explicitly requires the dismantling of armed groups in Gaza and the removal of Hamas from any governing role.

The terror organisation has acknowledged the video's authenticity.

The footage depicts masked gunmen, some displaying Hamas insignia, standing behind their victims as gunfire erupts.

Spectators can be heard shouting "Allah Akbar" and denouncing the executed as "collaborators".

President Trump acknowledged on Monday that the Islamist terrorists had received authorisation for temporary internal security measures, stating they wanted "to stop the problems" and "we gave them approval for a period of time".

The executions follow Hamas's admission last month that they had killed three individuals accused of Israeli collaboration.

The video circulated on social media with commentary questioning whether genuine peace could be achieved under such circumstances.

The twenty-point peace agreement mandates complete de-militarisation of Gaza and excludes Hamas from future governance, stipulating that Palestinian technocrats will manage daily administration instead.

However, the accord faces immediate challenges as Hamas has returned eight bodies of the 28 Israeli hostages who died in captivity.

Some Israeli families discovered their relatives had died only after expecting reunions with living captives.

The incomplete return of remains has provoked anger amongst bereaved families and threatens the agreement's stability.

Observers fear the execution footage indicates Hamas may resist surrendering weapons as they attempt to maintain their grip on power despite the accord's explicit requirements.

When questioned on Hamas' disarmament, Mr Trump told reporters at the White House: "They're going to disarm, because they said they would disarm. And if they don't disarm we will disarm them."

He added that US officials have spoken to Hamas and the group said it would give up its weapons.

Donald Trump signed the historic Israel-Hamas peace deal

President Trump said: "They know I'm not playing games," before adding the deadline will be "a reasonable period of time".

Sir Keir Starmer, who said the deal was not possible without the US President, has urged Hamas to return the remains of deceased Israeli hostages to their families in order to "honour the terms of the ceasefire".

The Prime Minister said: "The release of the bodies of the deceased hostages is a profoundly difficult moment for the families who have endured terrible and protracted pain over the last two years at the hands of Hamas.

"The loss of Yossi Sharabi will be felt deeply by his family, after Hamas so cruelly drew out their horror and denied them the right to grieve. I know from meeting his family just how loved Yossi was, and how devastating this ordeal has been. My thoughts are with them, and all of the hostage families.

"Hamas must now return the remaining deceased hostages and honour the terms of the ceasefire. Moving forward, we will continue to work with our partners to ensure the next phase of the peace plan is implemented in full."
