Two wounded after Arab terrorist opens fire on Border Police along Salah a-Din street in Israeli capital.

Two Israeli Border Police officers were seriously wounded after a terrorist opened fire on a police car traveling along Jerusalem's Salah a-Din street on Tuesday afternoon.

The attack occurred close to the Old City's Damascus Gate, where Arab terrorists regularly target Israeli security forces.

According to a Jerusalem Police spokesman, a terrorist gunman riding a motorbike opened fire on a patrol, wounding one officer, and then immediately fled the scene.

Other officers gave chase, and in an exchange of fire another officer was shot and seriously injured, before his comrades succeeded in shooting the terrorist dead.

Police recovered a Carl-Gustav style sub-machine gun from the terrorist's body, a cheaply-manufactured weapon which has been regularly used by Palestinian Arab terrorists in shooting attacks.

The injured officers have been evacuated to Hadassah Ein Karem hospital for treatment.

It is the second possible terrorist attack in the space of one hour Tuesday, after a 40-year-old Jewish man was stabbed by a Palestinian Arab attacker in Petah Tikvah, in what police say was likely a nationalistically-motivated attack.

In that incident, the victim - despite being stabbed repeatedly in the upper body - reportedly succeeded in wrestling the knife from the terrorist, and then stabbed him to death with his own weapon.

Earlier Tuesday, police in the Jerusalem thwarted two additional stabbing attacks.

In Jerusalem's Old City, officers shot and injured an Arab woman who attempted to stab them, while in Qalandiya a second Arab woman admitted to planning a stabbing attack after police discovered her hiding a knife.
