A South Korean spy plane without a pilot crashed near the border of North Korea, but there were no reported casualties on the ground, according to a South Korean military.

The airplane crashed near a factory in Pocheon, about 25 kilometers (15 miles) south of the Demilitarized Zone separating the two Koreas, shortly after it took off for a regular mission, said an official at the Joint Chiefs of Staff in Seoul.

The official denied to identify the model of the aircraft, specifically for security purpose. Yonhap news agency said it was an Israeli-made “Searcher” craft which can remain airborne for up to 14 hours.
