A blast caused by a fire at a weapons storage facility in eastern Baghdad on Friday set off rockets that hit neighbouring districts, killing at least four people and injuring a dozen others, police and hospital sources told Reuters news agency. 

The rockets damaged houses, shops, and cars at eight locations. 

A column of smoke was seen over Obaidi, a Shia neighbourhood near the industrial zone where the weapons depot is located.

The storage belongs to one of the Shia paramilitary groups of the Popular Mobilization Force (PMF), a coalition of militias that is taking part in fighting the Islamic State of Iraq and the Levant group (ISIL, also known as ISIS).
