Baghdad (CNN) At least 319 people have been killed in Iraq since the start of anti-government protests in October, according to the Iraqi Parliamentary Human Rights Committee.

Four protesters were killed in Baghdad on Saturday after Iraqi Security Forces pushed back hundreds of protesters and burnt several tents that were being used for an overnight sit-in, according to Iraqi activists.

Teargas and live ammunition was used by Iraqi security forces in the al Khalani commercial area, about 1 kilometer from Tahrir square -- Iraq's ground zero for demonstrations.

According to the Independent High Commission for Human Rights of Iraq nearly 15,000 have also been injured.

The higher death toll also includes two people who were killed Friday in the southern city of Basra during violent protests, the IHCR said in a statement. Basra is an oil-rich city located some 450 kilometers (280 miles) south of Iraq's capital Baghdad.
