Israel and Hamas will cease fire across the Gaza Strip border as of Friday, the United States said, bringing a potentially tenuous halt to the fiercest fighting in years.

Israeli Prime Minister Benjamin Netanyahu’s office said his security cabinet had voted unanimously in favour of a “mutual and unconditional” Gaza truce proposed by Egypt, but added that the hour of implementation had yet to be agreed.

Hamas and Egypt said the truce would begin at 2 a.m. (2300 GMT Thursday), after 11 days of Israeli-Palestinian hostilities.

In a televised address at 2200 GMT, U.S. President Joe Biden said both sides agreed the truce would begin “in less than two hours”.
