WASHINGTON (TheBlaze/AP) — American jet fighters and drones have conducted four more airstrikes on militants of the Islamic State of Iraq and Syria, taking out armored carriers and a truck that were firing on civilians in Iraq, according to the U.S. military.

Indications suggest that the strikes were successful in destroying the armored vehicles, the military said.

The strikes were spread out, with three before noon Eastern Daylight Time on Saturday and one about 3 p.m., U.S. Central Command said.

This is the third round of airstrikes against Islamic State forces by the U.S. military since they were authorized by President Barack Obama.
