BAKU (Reuters) - Two policemen were stabbed to death in the Azerbaijani city of Ganja during a demonstration on Tuesday that local media said was a protest against the arrest of a man accused of attacking the mayor.

Between 150 and 200 people took part in the protest and 40 were detained, the police said.

Ganja Mayor Elmar Veliyev was shot and wounded and his bodyguard was killed in the assassination attempt last week.
