Scores of Mexicans have marched in Chilpancingo, the capital of the restive state of Guerrero, to protest over the abduction and apparent massacre of 43 trainee teachers.
The latest protest comes after a wave of violent demonstrations in Guerrero that has seen the state legislature set alight, vehicles attacked and Acapulco’s international airport blockaded.
The students were reportedly incinerated in a bonfire at a garbage dump and their ashes thrown in a river.
Criticism of the government has intensified since authorities last week said evidence suggests the alleged victims were murdered by gunmen and drug gangs in collaboration with corrupt police and local politicians.
Around 100,000 people have died in violence linked to organised crime since 2007.
