WASHINGTON, Aug 9 (Reuters) - U.S. aircraft struck armored vehicles and other militant targets on Saturday in a second day of U.S. air strikes against the Islamic State, an extremist group threatening minorities in northern Iraq, U.S. Central Command said.
"At approximately 11:20 a.m. EDT, a mix of U.S. fighters and remotely piloted aircraft struck one of two (Islamic State) armored personnel carriers firing on Yazidi civilians near Sinjar, destroying the APC," Central Command said in a statement. Several other strikes followed, making for a total of four strikes.
President Barack Obama earlier on Saturday warned Americans the new U.S. military campaign against fighters from the Islamic State, a militant group that is encroaching on the Iraqi Kurdish capital Arbil, could take time. He spoke a day after the United States conducted its first air strikes in Iraq since U.S. troops withdrew in 2011. (Reporting by Missy Ryan; Editing by Mohammad Zargham)
