Additionally, an Egyptian citizen was killed and another injured during the same incident.
The suspected shooter has been apprehended and is currently under investigation by authorities, according to the source.
The policeman, part of the security services in Al-Mansheya neighbourhood, opened fire “randomly” while a group of Israeli tourists was visiting the Pompey's Pillar monument, the source added.
The shooting comes a day after Israel announced a “state of war” as Hamas killed hundreds of Israelis and captured tens of others in a surprise full-scale attack against Israeli cities.
Meanwhile, gun battles between Palestinian and Israeli combatants raged for a second day on Sunday.
