Kuala Lumpur -

Firefly Airlines says one of its domestic flights was forced to turn back shortly after take-off early on Thursday due to a landing gear problem.

None of the 68 people on board were hurt.

Firefly says the plane, a codeshare flight with its parent Malaysia Airlines, was unable to retract its landing gear shortly after leaving the Penang International Airport.

It says the plane returned and made a normal landing in Penang 35 minutes later.

The incident comes as Malaysia Airlines struggles in the aftermath since one of its Boeing 777 planes with 239 people on board disappeared March 8 while en route from Kuala Lumpur to Beijing.

Searchers are still looking for the plane, which is believed to have crashed in the southern Indian Ocean. - Sapa-AP
