Israel’s Prime Minister Benjamin Netanyahu has said “all the signs” are that a man who killed four soldiers in Jerusalem was a supporter of so-called Islamic State (IS).
But he did not outline evidence to support the claim.
The Palestinian man, who has since been shot dead, drove a lorry into a group of soldiers.
An emergency meeting of the Israeli security cabinet approved detention without trial for IS sympathisers.
Three women and a man, all in their twenties, were killed in the attack and 17 others were wounded, police said.
The attacker, identified as 28-year-old Fadi Qunbar, came from the Palestinian district of Jabel Mukaber in east Jerusalem, near to the attack site.
CCTV footage showed the truck ploughing at high speed into the soldiers, before reversing over the victims.
“He drove backward to crush more people,” eyewitness Leah Schreiber told reporters. “That was really clear.”
