The Venezuelan government ordered paratroopers Thursday to a border city where growing student protests began over two weeks ago, with President Nicolas Maduro angrily rejecting US calls for dialogue.

The nationwide demonstrations, led by students and the opposition, have left at least six people dead and dozens hurt in the biggest challenge to Maduro since he took power last year.

There have been near-daily protests and rallies, some of them violent, in the capital Caracas and other cities, over what Maduro's critics say are deteriorating economic conditions, rampant street crime, corruption and bleak job prospects.

Maduro's leftist government - which is sitting on the world's largest proven oil reserves - rushed a battalion of paratroopers to the city of San Cristobal, birthplace of the demonstrations that began on February 4.

The deployment came in response to claims from the government that Colombians were crossing the border there "to carry out paramilitary missions" in Venezuela.

Shops were closed and streets eerily quiet in San Cristobal, capital of the western border state of Tachira.

Maduro meanwhile threatened to yank CNN from the air waves over what he called the US broadcaster's "propaganda war." He shot back at Barack Obama, who has urged Venezuela to release detained protesters and address the "legitimate grievances" of its people.

Maduro's government said it "emphatically repudiates" Obama's remarks, accusing the US president of "a new and crude interference in the internal affairs of our country."

On Sunday, Maduro ordered the expulsion of three US diplomats, accusing them of meeting student leaders to conspire under the guise of offering them visas. Washington denies the allegations.

Maduro also came under attack from US pop icon Madonna, who Thursday accused Maduro's government of "fascism" over its handling of the roiling demonstrations.

Opposition leader Henrique Capriles challenged Maduro to prove his claims that the demonstrations were part of a conspiracy to overthrow his government.
