Cargo plane slides off runway in Hong Kong, killing two airport staff

Two Hong Kong airport security staff were killed early on Monday after a cargo plane from Dubai skidded off the runway on landing, collided with their security patrol vehicle and pushed it into the sea, Reuters reported.

The Boeing 747 involved in the deadliest airport incident in the financial hub in more than 25 years also fell into the water and was partially submerged, but all four crew members on board escaped.

The airport security staff were not breathing when rescued from the water, with one confirmed dead at the scene and another later at hospital, Reuters reported citing Steven Yiu, executive director of airport operations at Airport Authority Hong Kong.

The accident at the world's busiest cargo airport involved a plane operated by Turkish freight carrier ACT Airlines on behalf of Emirates, the Dubai-based airline said in a statement, according to Reuters.

Authorities are still investigating the exact cause of the crash.
