Donald Trump has threatened "massive bloodshed" in Gaza if Hamas fails to accept his peace terms.

On Monday, triple-header talks between Israel, the US and Hamas will take place in Egypt in a high-stakes bid to bring an end to the war after almost two years to the day.

And last night, Mr Trump confirmed negotiations lasting a "couple of days" had already begun.

Speaking to the press on the White House lawn, he said: "It's a great deal for Israel, it's a great deal for the entire Arab world, Muslim world, and world... We're very happy about it."

'Time is of the essence, or massive bloodshed will follow,' the President said

Hamas itself has said it would support the US proposal, but with conditions - while US Secretary of State Marco Rubio said that the group had already agreed.

America's 20-point plan includes the full release of all Israeli hostages, the eventual withdrawal of Israeli troops from the Gaza Strip, and no role for the terrorist group in the future running of Gaza.

But with the clock ticking, the President has issued a chilling ultimatum.

"I am told that the first phase should be completed this week, and I am asking everyone to move fast," Mr Trump said on Sunday.

"I will continue to monitor this centuries-old 'conflict'. Time is of the essence, or massive bloodshed will follow - something that nobody wants to see!"
