A cargo plane has gone missing off the coast of Pakistan. The plane, a Boeing 737, was on a flight from the United Arab Emirates to Karachi when it lost contact with air traffic controllers.

The aircraft was being operated by K2 Airways and had five crew members aboard. It reported a navigation system problem before rapidly descending and changing direction.

Further details about the incident, including the cause of the disappearance, are available from Pakistan's airport authority, which has reported that search and rescue operations are underway in the Arabian Sea.
