The incident took place on Sunday in the Venezuelan capital Caracas.

The deceased has been identified as Xiomara Soledad Scott, a 61-year-old woman, who worked as a nurse.

The gunman approached the queue on a motorbike and fired at them.

According to rector of the Central University of Venezuela, Cecilia García Arocha, more than seven million people took part in Sunday's polls.

Meanwhile, condemning the shooting, opposition spokesman Carlos Ocariz said, "We lament this very much, with great pain."

Following the statement, prosecutors said they'll investigate the incident.

Venezuelans will take part in an official vote on Jul 30.

Reacting to Sunday's polls, President Nicolas Maduro described it as 'meaningless'.

"They have convened an internal consultation with the opposition parties, with their own mechanisms, without electoral rulebooks, without prior verification, without further verification. As if they are autonomous and decide on their own," Maduro said.

Venezuela is fighting a tough time, as murder rate is soaring high.

Around 100 people have in political clashes since April.

The jettisoning oil prices have fueled their miseries.

Oil accounted for almost 95 percent of its export revenues.

The frequent fight between the incumbent and opposition have further weakened the country, who is now facing a shortage of food and medicine supply.

The opposition has been severe on Maduro, questioning his competence as the President and accusing him of mismanagement.

With the cash crunch, Maduro's cabinet was also forced to make cuts in several government-organised social programmes, taking a toll on his support base.
