Wealthy students led right wing protests that turned violent in Venezuela last week. These included armed attacks on government buildings.
One student, one government supporter and one police officer had been killed as Socialist Worker went to press.
Tens of thousands also marched in support of the government on Saturday in the capital Caracas.
President Nicolas Maduro is the political heir of popular left wing leader Hugo Chavez.
But he has presided over high inflation and growing insecurity—giving the right wing confidence to go on the offensive against the legacy of Chavez’s reforms.
For many it has brought memories of the 2002 coup attempt against Chavez. However the right is now more divided, with former presidential candidate Henrique Capriles Radonski distancing himself from the violence. Its grip on key state institutions has been considerably weakened.
Maduro this week expelled several US officials, although the US denied involvement in the protests. He also called on oil workers to march in defence of the government.
