Two shots were fired at a police bus outside Athens university early on Tuesday, ahead of a planned protest by high school and university students in a third week of anti-government demonstrations in Greece.
No-one was wounded in the shooting which took place around 0300 GMT outside the university, which students have occupied since the Dec. 6 police shooting of a 15-year-old sparked Greece's worst riots in decades.
If someone is shooting the tires on an empty bus, then it's a staged incident to justify further violence by the police against the protesters.
