On August 4, two Singapore Airlines planes hit each other's wings while preparing for take-off at the city-state's Changi Airport but no one was injured, the carrier said in a statement on August 5.

"It is reported that the wingtips of two aircraft came into contact while both aircraft were taxiing at low speed," company spokesman Stephen Forshaw said.

Both Boeing 777 aircraft suffered minor damage in the accident and the passengers were transferred to other aircraft for their flights to Rome and Copenhagen.

The airline gave no details on the number of passengers who were onboard when the incident occurred.

Forshaw said an investigation was underway with pilots of both aircraft assisting the relevant authorities.
