US forces have said there is an increase in the “sophistication” of resistance attacks, notably the use of landmines and explosives-rigged booby traps.
Two US soldiers were killed and at least six others wounded on Wednesday in separate attacks.
One soldier was killed and two wounded when a landmine exploded under a US military vehicle along a road leading to Baghdad airport in the Sidiyah district.
It came hours after another US soldier died and at least two others were injured when a bomb exploded as a convoy passed near Abu Gharib prison west of the capital.
US Central Command (Centcom) said the military convoy came under rocket-propelled grenade (RPG) attack.
US military officials said two blasts occurred when the second line of the convoy drove by.
