3 dead, 1 injured in Mexico prison riot

A fight between inmates at a northern Mexican prison has left three inmates dead and one injured.
Authorities in the northern border state of Tamaulipas say the fight followed a riot and mass escape at the facility.
The state security spokesman said today that control had been re-established at the prison in the state capitol, after inmates burned the demolished remains of illegally built shacks in a prison patio.
Authorities say inmates essentially controlled parts of the prison and used the shacks to cover a tunnel which they dug.
A total of 29 inmates escaped through the tunnel earlier this week, leading authorities to demolish the shacks.
