CARACAS - A Venezuela National Guard captain died on Monday after being shot in the head during a demonstration, the military said, the 29th fatality in six weeks of clashes between protesters and security forces.

General Padrino Lopez, head of the armed forces' strategic operational command, said the captain was shot late on Sunday at a street barricade set up by demonstrators in the central city of Maracay, in Aragua state.

"He was another victim of terrorist violence," Lopez said on Twitter, calling for an end to the confrontations. "Our armed forces don't repress peaceful protests, they protect them."

Since early February, students and hardline opposition leaders have been calling supporters onto the streets to protest against President Nicolas Maduro and his socialist government.

The demonstrators are demanding political change and an end to high inflation, shortages of basic foods and one of the worst rates of violent crime in the world.

The protests, however, show no signs of toppling Maduro, a 51-year-old former bus driver who narrowly won an election in April 2013 to replace his late friend and mentor, Hugo Chavez.

Tareck El Aissami, governor of Aragua state and a member of the ruling Socialist Party, said authorities arrested a "Chinese mercenary" near where the National Guard captain was killed.

Aissami said an "arsenal" was found in the man's home, and showed video of hundreds of rounds of different calibers.

He gave the man's Venezuelan identity card number, but did not elaborate further. The government has often talked of alleged assassination plans, but rarely provides many details.

In the western border state of Tachira, which has been hardest hit by the violence, residents rebuilt some barricades overnight on streets that the authorities had cleared.

In Puerto Ordaz, in the south of the country, Reuters witnesses said riot police clashed with hundreds of students. At least two government-owned vehicles were burnt by protesters.
