The shooting occurred days after unidentified attackers threw two hand grenades at the Saudi consulate in the city, Pakistan's commercial hub. No one was hurt in that attack.

"We condemn this attack. No one who carries out this kind of attack can be a Muslim," the ambassador, Abdul Aziz al-Ghadeer, said. He did not give details on the rank of the diplomat who was killed.

It's too early to determine who was behind the attack, the ambassador said, but he suggested "terrorists," a reference to Muslim militant groups such as al Qaeda, carried it out.
