Mass shooting at Mexican drug rehabilitation clinic leaves 24 dead

Gunmen have burst into an unregistered drug rehabilitation centre in Mexico and opened fire, killing 24 people and wounding seven.

Police in the north-central state of Guanajuato said the attack occurred today in the city of Irapuato.

Three of the seven wounded were in serious condition.

It appears the attackers shot everyone at the rehab centre; state police said nobody was abducted.

Guanajuato is the scene of a bloody turf battle between the Jalisco cartel and a local gang, and the state has become the most violent in Mexico.

No motive was given in the attack, but Governor Diego Sinhue said drug gangs appear to have been involved.
