Polls opened in Venezuela on Sunday in an opposition-organized vote to measure public support for President Nicolas Maduros plan to rewrite the constitution, against a backdrop of worsening political violence.
Dozens of people were queuing in Caracas neighborhoods including Chacaito and Los Palos Grandes before polling stations opened at 7:00 am (1100 GMT), according to the Democratic Unity Roundtable (MUD) opposition coalition.
