Students protesters marching to protest Venezuela's electoral commission and government have clashed with supporters of the late President Hugo Chavez.

Both sides were throwing bottles and rocks at each other Thursday afternoon, and scuffles broke out. It was unclear how many people have been injured.

About 300 students were marching through central Caracas when they encountered about 100 Chavez supporters, who began hurling rocks and bottles. The students returned the volley of objects, as fistfights broke out.

Police later fired tear gas to try to scatter the two groups.

The students were asking that the commission eliminate requirements that voters have their fingerprints recorded before voting. They were also demanding the government not interfere in politics ahead of an April 14 vote to replace Chavez.
