Police on Wednesday fired tear gas and water cannon at scores of rock-hurling students in the capital, Caracas, where about 3,000 students marched to mark a month since the first deaths in weeks of demonstrations.

Thousands of supporters and foes of President Nicolas Maduro took to the capital´s streets for rival rallies marking a month since the first bloodshed in the recent unrest around the South American OPEC nation.

Student radicals have vowed to continue the "Venezuelan Spring" protests. But despite the bloodshed and drag the actions have had on the county´s troubled economy, Maduro appears to be in little danger of being toppled.

Of the more than 1,300 people arrested since anti-government demonstrations began at the start of February, 92 are still behind bars, according to the government. Those held include 14 security officials, some of whom are implicated in the deaths of two of those shot in the February 12 rallies. More than 300 people have been injured in the unrest.

Since the protests began, opposition leaders and students, as well as government authorities, have accused each other of backing radical groups that attack demonstrations with firearms.
