The source told Shafaq News agency that the explosion targeted a supply convoy of the Coalition on al-Anbar highway.
The attack resulted in no damage and casualties.
The attack is the fourth of its kind today, after a similar bombing attempt in al-Diwaniyah and two others in Dhi Qar. The previous attacks resulted in only material damage.
Observers believe that Iran-backed Iraqi factions orchestrate these nearly daily attacks against the convoys of the US-led Coalition in Iraq.
