Opposition parties have called for a white-clad "silent" protest across Caracas city on Saturday (22 April) in remembrance of those killed in the unrest this week.

Video taken by locals showed residents throwing bottles and other objects out their windows at the gunmen in the streets below, shouting "murderers".
