BAGHDAD (AP) Security forces in Iraq shot dead 27 anti-government protesters in a 24-hour period, amid spiraling violence in the capital and the countrys south, as Iran condemned the burning of its consulate.

Security forces Thursday fired live ammunition, killing four protesters and wounding 22 on the strategic Ahrar Bridge in Baghdad, security and medical officials said.

Violence across southern Iraq continued throughout the night, with security forces killing 23 protesters and wounding 165 since Wednesday evening. Protesters closed roads and police and military forces were deployed across key oil-rich provinces.

In Baghdad, protesters attempted to cross the Ahrar Bridge leading to the heavily fortified Green Zone, the seat of Iraqs government, nearby. Protesters were occupying parts of three bridges - Jumhuriya, Sinak and Ahrar - all leading to the fortified area. Officials spoke on condition of anonymity in line with regulations.

Protesters had set fire to the Iranian consulate in the holy city of Najaf late Wednesday, in one of the worst attacks targeting Iranian interests in the country since the anti-government protests erupted two months ago. The Iranian staff were not harmed and escaped out the back door.

Anti-government protests have gripped Iraq since Oct. 1, when thousands took to the streets in Baghdad and the predominantly Shiite south. The largely leaderless movement accuses the government of being hopelessly corrupt and has also decried Irans growing influence in Iraqi state affairs.
