Two Venezuelan opposition leaders, Leopoldo López and Antonio Ledezma, have been re-arrested, relatives of the pair say.They were under house arrest after accusations of inciting violence during anti-government protests in 2014.
Their families said they did not know where the two had been taken.
The move comes just two days after a controversial vote for a constitutional assembly saw violence on the streets, with at least 10 people killed.
President Nicolás Maduro convened the assembly to rewrite Venezuela's constitution amid spiralling anti-government protests on 1 May.
Looks like a night of the Long knives in Venezuela ....also called Operation Hummingbirb.
