ATHENS, Dec. 30 (Xinhua) -- A group of gunmen opened fire early Monday outside the German ambassador's house here, causing no injuries, police said.
Four men armed with AK-47 rifles approached the property in a northern Athens suburb before dawn and opened fire from outside, according to early information.
It is not the first time a German diplomat's house has been attacked in Athens. In May 1999, the now disbanded Greek guerilla group "November 17" fired a rocket at a residence, again causing no injuries.
Greek Prime Minister Antonis Samaras and Public Order Minister Nikos Dendias have contacted the diplomat by telephone. Counter terrorism experts are investigating the case.
