ATHENS (Reuters) - A homemade bomb exploded in a central Athens avenue late on Thursday, causing serious damage to a state building and shops but no injuries, police said.
A police official said it exploded outside the building of an agency managing state property about 250 metres (yards) from Athens central police headquarters.
There was no warning and no group had claimed responsibility for the attack. Police experts at the scene were investigating what kind of explosive device was used.
The government is still reeling from the worst riots in decades in December, provoked by the fatal police shooting of a 15-year-old and fuelled by anger at youth unemployment and economic measures.
Last week, Greece’s most militant guerrilla group Revolutionary Struggle said it was behind two attacks against Citibank branches in the Greek capital.
The group has claimed responsibility for a series of attacks against police and ministries, including a rocket-propelled grenade attack against the U.S. embassy in Athens, in 2007.
