2 people killed in deadly bomb explosion in Baghdad, three others killed in clashes

The hub of anti-government protests that have gripped Iraq for weeks was hit by deadly bomb blast explosion in Central Baghdad after the clashes between protestors and Iraqi security forces resumed.

Two people were killed, and 12 others were injured after an improvised explosive device that was placed under a vehicle went off late on Friday, according to security sources.

Since the demonstration began in early October, it was the first such incident in the capital although it was not immediately clear whether the explosion close to Tayaran Square and Tahrir Square targeted the protesters.

On the other hand separately on Friday, Iraqi security forces fired rounds fo live bullets and tear gas towards demonstrators in Central Baghdad, killing at least three people and wounding 25 others.

Protesters had repeatedly regrouped from under clouds of tear gas as they fought to tear down a concrete wall blocking access to Khilani Square.

Security forces erected the barrier to keep the demonstrations from crossing a bridge that leads to the fortified Green Zone, which houses government buildings and foreign embassies.

The clashes come as rights groups condemned the use of excessive force by police and security forces when dealing with peaceful demonstrators, as well as medical workers and ambulances.

Since October 1, Iraqis have been pouring onto the streets of Baghdad and southern cities to protest against corruption and the government's failure to deliver essential services and economic opportunities.

The protesters' demands have since widened to include the resignation of the government and a complete overhaul of the country's political system, which was established after a US-led invasion that critics say has allowed specific individuals and groups to enrich themselves and expand their influence.

At least 320 people have died since October 1 with more than 15,000 wounded during the protests, according to the Iraqi Parliament's human rights commission.
