Venezuelan President Nicolas Maduro said he hopes to talk with the opposition after their leaders meet Sunday with visiting South American foreign ministers.

The Democratic Unity opposition coalition (MUD) is scheduled to meet in the capital Caracas with the foreign ministers of Brazil, Colombia and Ecuador, as well as the ambassador from the Vatican.

Venezuelan President Nicolas Maduro pledged Friday to send oil and diesel to the Palestinian Authority, as part of agreements signed with its leader Mahmud Abbas during his visit to Caracas.

Venezuela, which sits atop the world's largest oil reserves, said it would provide an initial shipment of 240,000 barrels of oil, but gave no details as to how it would send them.

Venezuela's main opposition coalition said Thursday it will meet with South American foreign ministers and a Vatican envoy on Sunday to discuss stalled political talks with the government.

The opposition had suspended the talks earlier this week in response to a new wave of arrests of anti-government protesters.

Venezuelan police arrested 105 people and fired tear gas at anti-government student protesters who hurled stones and fireworks Wednesday at a ministry building in the capital, officials said.

The students, who were marching to demand the release of protesters arrested in recent days, massed in eastern Caracas. But the demonstration quickly became violent when they targeted the Tourism Ministry and riot police intervened.

Venezuela's opposition said Tuesday it has suspended working group-level talks with the government because of mass arrests of student protesters last week.

"These actions show that the government does not want dialogue, when it has been asked several times to stop this very aggressive position," said Juan Jose Medina, the coordinator of the opposition delegation.

Venezuela has set free most of more than 200 people detained when authorities demolished protest camps last week, officials said Sunday.

The demonstrators had been rounded up in raids on Thursday, holdouts in bastions of a months-long and at times deadly protest movement. Officials initially said 243 people were arrested.

A U.S. congressional panel passed a bill Friday that would impose sanctions on those responsible for human rights abuses against anti-government protesters in Venezuela.

The House Foreign Affairs Committee approved the "Venezuelan Human Rights and Democracy Protection Act," clearing a first legislative hurdle.

A Venezuelan policeman died after he was shot in the neck Thursday in clashes with anti-government demonstrators in Caracas angered by pre-dawn raids on their protest camps.

Authorities demolished the camps and detained 243 people in the surprise early morning raids, striking at the remaining bastions of a months-long and at times deadly movement led by students against the leftist administration of President Nicolas Maduro.

Venezuelan authorities demolished four protest camps and detained 243 people early Thursday, striking at the remaining bastions of a months-long and at times deadly anti-government protest movement.

Riot police swept through the camps in surprise raids that began at 3 pm, Minister Miguel Rodriguez Torres said, claiming the sites occupied by students were "being used by more violent groups to commit terrorist acts."

Venezuela has arrested two National Guards over the death of a student in anti-government protests that swept the country in recent months, the government said Tuesday.

In all, 41 people have died since students and other opponents of the leftist government of President Nicolas Maduro took to the streets in February to protest rampant crime, runaway inflation and shortages of basic goods.
