"ATHENS, Greece: A bomb exploded outside Greece's Ministry of Environment and Public Works on Sunday, causing slight damage, officials said. No injuries were reported.

The bomb went off at 4:50 p.m. (1450 GMT) and smashed some windows at the ministry. Twenty-five minutes earlier, an unknown man had called daily newspaper Eleftherotypia to warn of the impending explosion.

"A bomb will go off in 25 minutes," he said. "This is not a hoax, inform people immediately."

The ministry's general secretary for Public Works and a few employees working at the time were evacuated by police.

Police officials, who found the remains of the bomb at a nearby trash can, said its makeup was similar to that of other bombs detonated by terrorist organizations "Popular Revolutionary Action" and "Revolutionary Struggle."
