Baghdad [Iraq], April 20 (HBTV): At least three people were injured following five explosions at a pro-Iran military base in Iraq on Saturday, CNN reported, citing a security official. 

However, the reason behind the explosions is not known as yet. 

The blasts, notably, took place at a site belonging to the Popular Mobilization Units (PMU), as per Muhannad al-Anazi, a member of the Security Committee in Babylon Governorate, south of Baghdad. 

The investigation into the blasts that occurred "at the Kalsu military base in the Al-Mashrou district on the highway, north of the Babylon Governorate," is underway.  

Israeli and US officials said neither was involved in the blast, a day after a military strike on Iran which has been attributed to Israel.  

Known alternatively as the Popular Mobilization Forces, the PMU is an Iraqi paramilitary group that is mostly supported by Shiite Iran. The PMU, in contrast to other Iran-backed organizations in the area, is affiliated with the local administration and has strong ties to Shiite blocs in Iran that have dominated Iraqi politics for a long time, according to CNN.
