A makeshift bomb went off late outside the offices of National Insurance company in central Athens causing damage to the building and nearby cars but no injuries, police said.

"There was a warning phone call to a newspaper about 15 minutes before the explosion but no claim of responsibility," a police official said.

Police said the explosive device was placed near the entrance of the insurance company's building, located near the Ledra Marriott hotel. The company is a subsidiary of National Bank, the country's biggest lender.

The incident is the latest in a series of gas canister and bomb attacks by leftist and anarchist groups that have rocked Greece since the police shooting of a teenager sparked the country's worst riots in decades in December 2008.
