Authorities in southern India say they killed five prisoners, including one accused of terrorism, when they tried to escape from a police van.

Police were transferring the five men Tuesday from Warangal city to a court in Hyderabad.

The head of Telangana state police, Anurag Sharma, said the five attacked the accompanying officers and tried to escape, but were shot dead.

The five included alleged Islamic extremist Syed Viqaruddin, who has been held for two years on charges of killing two policemen in Hyderabad.
