BAGHDAD - Three people died and 24 were wounded in renewed clashes in central Baghdad between anti-government demonstrators and security forces, bringing the death toll for the day to seven, Iraqi security and hospital officials said Thursday.

The clashes, the deadliest in recent days, erupted on the capital's Rasheed Street, a cultural centre known for its old crumbling buildings. Security forces fired live ammunition, tear gas and sound bombs to disperse dozens of protesters.

The officials spoke on condition of anonymity in line with regulations.

Two protesters were killed when tear gas canisters struck them and one was killed by live ammunition. The clashes took place on the street near Ahrar Bridge, the officials say.

Earlier, four protesters were killed in fighting near Ahrar and Sinak bridges. One protester was killed when security forces used live rounds to repel demonstrators on Ahrar Bridge. The other protester was killed when a tear gas cannister was fired on Sinak Bridge, hitting him in the head.

Two protesters later succumbed to their injuries.

Protesters have been occupying parts of Baghdad's three main bridges - Sinak and Ahrar and Jumurhiya - leading to the heavily fortified Green Zone, the seat of Iraq's government.

Fighting also resumed overnight in the Shiite holy city of Karbala, south of Baghdad, between protesters and security forces.

Tents have been set up under the bridges and also on central Tahrir Square, the epicenter of the protest movement, where first-aid volunteers treat those wounded by pieces of exploded tear gas cannisters and live fire.

“Around 1:30 a.m., the shooting started with live ammunition, tear gas and sound grenades,” said one volunteer, speaking on condition of anonymity for fear of government reprisal. “There were martyrs and we received several injured” people with breathing difficulties and bullet wounds.

In Karbala, the protesters threw crudely made fire bombs, also known as Molotov cocktails, at security forces while anti-riot police responded by throwing stones at the protesters.

Dozens of demonstrators had attacked the Iranian Consulate in this city earlier in November, scaling concrete barriers and saying they rejected the influence of the neighbouring country in Iraqi affairs.

At least 320 protesters have been killed and thousands have been wounded since the unrest began on Oct. 1, when demonstrators took to the streets in Baghdad and across Iraq's mainly Shiite south to decry rampant government corruption and lack of basic services despite Iraq's oil wealth.

The leaderless movement seeks to dismantle the sectarian system and unseat the government, including Prime Minister Adil Abdul-Mahdi.
