A candidate for the new body in Venezuela’s southeastern town of Ciudad Bolivar, 39-year-old lawyer Jose Felix Pineda, was killed from multiple shots fired by assailants who broke into his home overnight, prosecutors said.

He was the second candidate to be murdered, after the July 10 death of another, Jose Luis Rivas, as he was campaigning in the northern city of Maracay.

In the west of Caracas, national guard troops fanning out to put down any disruption to the election used armored vehicles and fired shots to disperse protesters blocking roads.

Video posted on Twitter showed troops smashing down a metal gate and entering to the sounds of gunfire, and what appeared to be an armored vehicle on fire.

The opposition has called for a boycott and mass demonstrations against the election, which it calls a bid by Maduro to install a dictatorship with the backing of the military.

Four months of protests against Maduro and the new assembly have left more than 100 people dead.
