A widespread power cut affecting much of Venezuela has continued throughout the night, ahead of protests planned for today.
Hospitals struggled to cope, and at least one patient died when her respirator stopped working.
The power cuts, which started on Thursday, have been caused by problems at a major hydro-electric plant.
Meanwhile, President Nicolás Maduro and the US-backed opposition which is trying to oust him have blamed each other for the outage!
Venezuela depends on its vast hydro-electric infrastructure rather than on its oil reserves, for its domestic electricity supply. However, decades of under-investment have damaged the major dams, and therefore sporadic blackouts are common.
