Erbil, Up to four or five explosions rocked Kurdistan capital Hewler today.
Some reports speaks of four car bombs detonated near the headquarters of Iraqi Kurdish security services, followed by gunfire. It is believed the explosions caused a yet unspecified number of casualties. Some reports say at least 5 people have died and over 20 injured.
A senior security official said the first blast was a suicide car bomb, while an explosives-rigged ambulance was detonated when people rushed to check for casualties.
Smoke could be seen rising in the air, as ambulances raced to the scene.
While much of Iraq, since the 2003 invasion by U.S. and its allies, is still witnessing virtually daily violence leaving hundreds of dead people each month, the three-province Kurdistan region in the country's north has been relatively quiet.
Sunday's blasts were the first to hit Erbil since May 2007, when a truck bomb exploded near the same asayesh headquarters, killing 14 people and wounding more than 80.
The blasts came a few days after the region's parliamentary elections, which saw the opposition Gorran movement in second place ahead of Iraqi President Jalal Talabani's party.
