Mexico missing case: Attack on governing party offices
Protesters in Mexico have set fire to the governing PRI party's offices in south-western Guerrero state to vent their anger at the official handling of the case of 43 missing students, the BBC reported.
Their disappearance more than six weeks ago from the town of Iguala has sparked a series of sometimes violent protests.
Officials say local gang members have confessed to killing the students and burning their bodies.
But remains found nearby have not yet been matched to the missing.
About 1,000 people marched in the Guerrero state capital, Chilpancingo, before unrest broke out.
A group of protesters fought running battles with police, throwing stones and petrol bombs.
Officials said three police officers and two journalists were injured in the clashes.
