NEW DELHI: Iraq's security services said there were no warplanes or drones in the air during overnight explosions that rocked Iraq’s military base housing a coalition of pro-Iranian armed groups.

An explosion occurred overnight at an Iraqi military base housing a coalition of pro-Iranian armed groups on Saturday. It was an airstrike at the military base in Babylon province south of Baghdad, where Iraq's Popular Mobilization Forces, or Hashed al-Shaabi, is stationed, according to officials.

An Iraqi security forces media unit said in a statement that air defence command reported "no drones or combat aircraft in the airspace of Babylon province before or during the explosion".   

One PMF fighter was killed and six were wounded, two sources at a hospital in the nearby city of Hilla said.

"The blast has caused material damage and injuries," PMF said in a statement. The team was investigating the matter.

While earlier, the ministry of interior official said in a statement the aerial bombing had killed one person and wounded eight others, the military source further reported three Iraqi military personnel had been wounded in a strike.

However there were no immediate claims of responsibility. But shortly after the explosion, the US military said its forces were not behind the reported strike in Iraq.

"The United States has not conducted air strikes in Iraq today," US Central Command (CENTCOM) posted on social media platform X, adding that reports that American forces had carried out a strike were "not true."

Earlier on Friday, Israel carried out an attack on Iranian territory days after Iran struck Israel with a barrage of drones and missiles. 

Israeli officials made no public comment on Friday's attack and Iranian officials have played down its significance.
