WASHINGTON- US military aircraft dropped humanitarian aid to Iraqis under threat from hardline militants in northern Iraq for the second straight night, the Pentagon said on Friday.

"This airdrop was conducted from multiple airbases within the US Central Command area of responsibility and as with last night, included one C-17 and two C-130 cargo aircraft that together dropped a total of 72 bundles of supplies," the Pentagon said in a statement released late on Friday.

The cargo planes were accompanied by two F-18 fighter jets from the USS George H.W. Bush, a US aircraft carrier positioned in the Gulf, it said.
