Protesting farmers have clashed with Peruvian police in a confrontation that left a protest leader dead and at least 17 people, including two police officers, injured.

Police say activist Jorge Altamirano Roman was shot and killed Monday as officers outside the southeastern city of Andahuaylas tried to control a crowd of at least 1,000 farmers. The protesters had blocked roads to the city, set fire to vehicles and attacked people and property with rocks and clubs.

The farmers, from one of Peru's poorer regions, Apurimac, were protesting high fertilizer and seed prices, and poor transportation links, among other grievances.

Elsewhere in Peru, a nationwide teachers' strike is underway to protest a new educational reform law.
