ATHENS (AFP) - The police in Greece early on Friday were investigating a strafing attack on the Israeli Embassy in Athens in which nobody was injured, a police source said.

The shots were apparently fired from a motorcycle with two persons passing in front of the embassy, which lies on the corner of a busy highway, the police said.

Another two persons on a second motorcycle are suspected of participating in the 3.20am attack.

Early evidence suggests a Kalashnikov assault rifle was used, the police said. Bullet casings collected from the scene are to be examined by Greece's anti-terrorist squad for possible matches to other attacks, the police said.

The incident comes two days after a Palestinian official died following a confrontation with Israel soldiers in the West Bank.

There is strong condemnation in Greece of Israel's policies in the West Bank and Gaza, with many protests held in support of the Palestinians.

Embassies and diplomatic vehicles in Greece have been targeted in attacks by far-left groups in recent years.

The residence of the German ambassador in Athens has been hit twice - with two assault rifles in 2013 and a rocket in 1999. Nobody inside was hurt.

In 2007, another rocket was fired at the US Embassy in Athens without injuring anyone.

All three attacks were claimed by far-left groups, two of which have since been dismantled by the police.

The group involved in the 2013 attack on the German residence, the People's Fighter Group, is still at large.
