Athens: Unidentified attackers on a motorcycle threw an explosive device at the French embassy in central Athens early on Thursday, wounding a guard, police said, in an attack that came less than a week before US President Barack Obama visits the city.
"It was probably a hand grenade," one official told Reuters. "The building was not damaged, only externally, on the pavement. One officer, who was at the spot, was slightly injured."
The attackers were riding a motorcycle, according to footage from security cameras, another official said.
The explosion was heard in central Athens.
Small-scale attacks on businesses, police, politicians and embassies are frequent in Greece, with its long history of political violence.
