Unidentified groups or individuals set off explosives as the vehicles passed in the southern provinces of Al-Muthanna and Dhi Qar, central Baghdad and eastern Saladin.
The reports issued by the Saberin news site do not give a number of victims, although they do give an account of damage to the roads and the military and logistical equipment carried on the trucks.
The number of attacks against US interests in Iraq has risen in recent months as part of a majority rejection of their presence in the country.
In July 2021, Iraqi Prime Minister Mustafa al-Kazemi and US President Joe Biden signed an agreement whereby the US troops would return home.
However, one of the points of the agreement stipulated the permanence of some 2,500 military personnel as advisers and training personnel.
The Iraqi Resistance warned that they will continue their attacks against the Americans regardless their role, because they consider them an occupying force.
