Two Palestinians on Friday opened fire on a group of Israeli officers just outside the walled Old City in annexed east Jerusalem, while a third stabbed a border policewoman a short distance away.
The three perpetrators, all from the West Bank, were shot dead, and the policewoman, Hadas Malka, a 23-year-old staff sergeant major, was taken to hospital in critical condition and later died of her wounds.
"Instead of condemning the attack, Fatah... Issued a statement in which it condemn(s) the officers who killed the terrorists, and praised the murderers as heroes," Netanyahu said, referring to Palestinian president Mahmud Abbas' party.
The Israeli premier was apparently referring to a Fatah poster mourning the "martyrdom" of the three perpetrators in the "heroic" operation, and a series of tweets on a Fatah account referring to their "glory and immortality".

"Of course, the Palestinian Authority is refusing to condemn the murder and the same authority will now pay financial compensation to the murderers' families," he said at the start of the weekly cabinet meeting.
"I call on the countries of the world to condemn the murder and those who praise it, and to demand an immediate cessation of Palestinian Authority payments to the families of terrorists, something that only encourages terror," Netanyahu said.
Israel, however, said it saw no evidence of such a decision, and the Palestinians wouldn't confirm.
Compensation payments to the families of "martyrs" who die carrying out attacks on Israelis are one of the sticking points in the moribund Middle East peace process.
The Israeli policewoman was buried late yesterday in a military cemetery in the southern city Ashdod.
Friday's attack is the latest in a wave of unrest that has rocked Israel and the occupied Palestinian territories since October 2015.
