Greek police say a hand grenade attack outside the French Embassy in Athens has lightly wounded a policeman.

Authorities say the policeman, who had been on guard outside the embassy, was wounded when unknown assailants threw a hand grenade outside the embassy building, located opposite Parliament on a major avenue in the centre of the Greek capital, early Thursday.

Police shut down the area to vehicles and pedestrians, while anti-terrorism forensics experts combed the scene for evidence. Police said the attack was apparently carried out by two people on a motorbike, and a bike matching the description was later found in a central Athens neighborhood and was being examined.

Greece has a history of domestic militants who periodically carry out bomb or shooting attacks against authorities, diplomatic locations or businesses.
