Greek anti-terror squad investigates after a bomb was defused near riot police headquarters

Greece’s antiterrorism squad is investigating after the headquarters of the national riot police was targeted with a bomb that was defused before it could explode

ATHENS, Greece -- Greece's antiterrorism squad is investigating after the national riot police headquarters was targeted Monday with a bomb that was defused before it could explode, as police union members protested increasing violence against officers in the force.

Authorities had been alerted after an anonymous caller warned a newspaper that the bomb would explode in 45 minutes and described where it had been planted. That gave bomb disposal experts time to find and defuse the device.

The bomb had been left in a copse near the riot police headquarters outside the city center and close to a university campus, police said. There was no claim of responsibility.

Such bomb attacks have long been associated with domestic far-left militants.

Many in Greece accuse riot police of brutality against demonstrators during the myriad protests held by leftwing groups or students who often attack police, sparking widespread clashes. Violence is also common during sports events, where fans attack police when not fighting each other.
