A spokesperson for the Department of Foreign Affairs say they are providing consular assistance to the family of an Irishman who was killed in a plane crash in Hawaii.
The man is from the Midlands and is believed to have been the pilot of a plane offering sky-diving trips.
The aircraft came down just outside Port Allen Airport on the island of Kauai on Monday.
Two instructors and two tandem jumpers are also believed to have died in the crash.
