North Korea is developing an unmanned attack aircraft using US target drones imported from the Middle East, a report said Sunday.

They are based on MQM-107D Streaker target drones, which are used by the US army, and imported from a Middle East nation believed to be Syria, Yonhap news agency reported.

It cited an anonymous Seoul military official, adding that the country would likely deploy them, once completed, near its maritime border with the South on the Yellow Sea.

The US drone, which flies at 40,000 feet (12,000 meters) at a maximum speed of 575 miles (920 kilometers) per hour, is commonly used for testing missiles.
