In pics: ISIS claims fatal stabbing of Israeli policewoman

ISIS, for the first time, claimed responsibility for the fatal stabbing of an Israeli policewoman outside Jerusalem's Old City

Three Palestinians attacked officers at Damascus Gate in annexed east Jerusalem late on Friday before being shot dead by security forces

But Hamas, the Palestinian Islamist group that runs the Gaza Strip, dismissed the claim

In an online statement, IS said jihadist fighters had targeted a "gathering of Jews", warning that "this attack will not be the last".

The assault took place as tens of thousands of Palestinians held night prayers at the nearby Al-Aqsa mosque compound.

Israeli authorities say most of the Palestinians killed were carrying out knife, gun or car-ramming attacks.
