Five wounded in bomb attack on Arabiya TV in Baghdad
The blast took place in Baghdad's western district of Harithiya, the source said.
Arabiya TV said their reporters were not at the office at the time of the attack, and that three people were wounded.
Iraq is on high alert for insurgent attacks after a March 7 national election produced no clear winner and left the country adrift in political uncertainty.
Overall violence has dropped sharply since the height of sectarian carnage in 2006-7. But daily bombings and killings continue, suggesting insurgents are trying to exploit the vacuum as political rivals jostle for power.
