WASHINGTON (AFP) - The Pentagon confirmed Thursday that Iranian forces shot down a US naval surveillance drone but insisted the plane turned into in global air space, not that of Iran.

The BAMS-D drone changed into downed by way of an Iranian surface-to-air missile machine even as flying in global airspace over the Strait of Hormuz, a US critical Command spokesman, military Captain bill urban, stated in a statement. He said it happened at 2335 GMT Wednesday.

"Iranian reviews that the plane changed into over Iran are fake," he brought. "This was an unprovoked attack on a US surveillance asset in international airspace."
