A security source, speaking on condition of anonymity, told Arabic-language al-Sumaria television network that the blast took place when the trucks were moving along a road in al-Rasheed district of the southern Baghdad neighborhood of Yusufiya on Monday.
The source added that the explosion resulted in the injury of a police officer.
No group has claimed responsibility for the attack yet, which is the latest in a series of explosions that have targeted US occupation forces over the past few months.
On February 11, a roadside bomb struck a convoy of trucks belonging to the US-led coalition forces as it was moving along a highway in the town of Latifiya, situated 40 kilometers (25 miles) south of Baghdad. The blast did not cause any casualties.
The attacks come amid rising anti-US sentiment, which has intensified since last year’s assassination of top Iranian anti-terror commander Lieutenant General Qassem Soleimani in Baghdad.
General Soleimani, the commander of the Quds Force of Iran’s Islamic Revolution Guards Corps (IRGC), and his Iraqi trenchmate Abu Mahdi al-Muhandis, the deputy head of the Popular Mobilization Units, were targeted along with their companions on January 3, 2020 in a terror drone strike authorized by former US president Donald Trump near Baghdad International Airport.
Two days after the attack, Iraqi lawmakers approved a bill that requires the government to end the presence of all foreign military forces led by the US in the country.
Currently, there are approximately 2,500 American troops in Iraq.
