CARACAS (Reuters) - Gunmen killed two more people during political unrest in Venezuela on Monday, bringing the total number of deaths to 12 this month, as anti-government protests entered a fourth week with mass “sit-ins” to press for early elections.

A 42-year-old man who worked for local government in the Andean state of Merida died from a gunshot in the neck at a rally in favor of President Nicolas Maduro’s government, the state ombudsman and prosecutor’s office said.

Another 54-year-old man was shot dead in the chest during a protest in the western agricultural state of Barinas, the state prosecutor’s office added without specifying the circumstances.

Seven others were injured in both places.

The latest deaths come amid a month of protests that have sparked politically-motivated shootings and clashes between security forces armed with rubber bullets and tear gas and protesters wielding rocks and Molotov cocktails.

Eleven people have also died during night-time looting.

The ruling Socialist Party accuses foes of seeking a violent coup with U.S. connivance, while the opposition says he is a dictator repressing peaceful protest.

The opposition’s main demands are for elections, the release of jailed activists and autonomy for the opposition-led congress. But protests are also fueled by the crippling economic crisis in the oil-rich nation of 30 million people.

“I have an empty stomach because I can’t find food,” said Jeannette Canozo, a 66-year-old homemaker, who said police used rubber bullets against protesters blocking a Caracas avenue with trash and bathtubs in the early morning.

Demonstrators wore the yellow, blue and red colors of Venezuela’s flag and held signs denouncing shortages, inflation and violent crime as they chanted: “This government has fallen!”

In the capital, they streamed from several points onto a major highway, where hundreds of people sat, carrying bags of supplies, playing card games, and shielding themselves from the sun with hats and umbrellas.

In western Tachira, at another of the “sit-ins” planned for all of Venezuela’s 23 states, some played the board-game Ludo, while others played soccer or enjoyed street theater.

At protests in southern Bolivar state, a professor gave a lecture on politics while some people sat down to play Scrabble and others cooked soup over small fires in the streets.

‘WE’RE NOT GOING’

Following a familiar daily pattern, the demonstrations were largely peaceful until mid-afternoon, when scattered skirmishes broke out and the shooting incidents occurred.

“In the morning they seem peaceful, in the afternoon they become terrorists and at night bandits and killers,” Socialist Party official Diosdado Cabello said of the opposition. “Let me tell them straight ... Nicolas (Maduro) is not going.”

This month’s turbulence is Venezuela’s worst since 2014 when 43 people died in months of mayhem sparked by protests against Maduro, the 54-year-old successor to late leader Hugo Chavez.

The latest protests began when the pro-government Supreme Court assumed the powers of the opposition-controlled congress. The court quickly reversed course, but its widely condemned move still galvanized the opposition.

The government’s disqualification from public office of two-time presidential candidate Henrique Capriles, who would be an opposition favorite to replace Maduro, gave further impetus to the demonstrations.

“I’m staying here until 6 p.m. We’re simply warming up because the day will come that we are all coming to the street until this government goes,” said Gladys Avariano, a 62-year-old lawyer, under an umbrella at the Caracas “sit-in.”

More than 1,400 people have been arrested this month over the protests, with 636 still detained as of Monday, according to local rights group Penal Forum.

Facing exhortations from around the world to allow Venezuelans to vote, Maduro has called for local state elections - delayed from last year - to be held soon.

But Cabello said opposition parties could be barred from competing. And there is no sign the government will allow the next presidential election, slated for late 2018, to be brought forward as the opposition demands.

Given the country’s economic crisis, with millions short of food, pollsters say the ruling Socialist Party would fare badly in any free and fair vote at the moment.

Trying to keep the pressure on Maduro, the opposition is seeking new strategies, such as a silent protest held on Saturday and Monday’s “sit-ins”.

While some small demonstrations have been held in poorer and traditionally pro-government areas, most poor Venezuelans are more preoccupied with putting food on the table.
