A Venezuelan human rights group says at least four people died in two days of protests after opposition leader Juan Guaido called for a military uprising.

The Venezuelan Observatory of Social Conflict says the dead from the unrest on Tuesday and Wednesday include two people who were shot in the city of La Victoria and two others hit by gunfire in Caracas, the capital.

Human rights activists say at least 230 people were injured and 205 were detained during the clashes between protesters and police.

Mr López sought refuge there on Tuesday after appearing with opposition leader Juan Guaidó to call for a rebellion to oust President Nicolás Maduro.

Speaking to reporters, he said more "military movements" were on the way.

A defiant Mr Maduro has said "any coup plotter" would be defeated. Four people have died in clashes since Tuesday.

Both President Maduro and Mr Guaidó claim they have the support of the armed forces and have been staging rival rallies in the capital.

In January, Mr Guaidó declared himself Venezuela's interim leader and he has the support of more than 50 countries including the US, UK and most Latin America nations.

But Mr Maduro - who is backed by Russia and China - has refused to cede power.

In a statement, the Spanish foreign ministry said that under no circumstance would it force Mr López to leave the embassy building.

Spain's government also said that Mr López and his family had sought safety in their embassy but had not claimed political asylum.

Speaking from the diplomatic mission, Mr López said he had met senior Venezuelan military officers before Tuesday's events.
