A blast on a passenger airplane punched a hole in the side of the fuselage soon after take off from the airport at Somalia's capital Mogadishu, police said Wednesday.

The airplane, operated by Daalo Airlines and flying from Mogadishu to Djibouti with around 60 passengers, landed safely.

Two passengers were slightly injured, police said.

"The passenger plane made an emergency landing soon after it took off on Tuesday, and there was a damage on one side of the aircraft over the right wing," Somali police officer Mohamed Ise said.

He added it was not clear what had caused the explosion and fire and that investigations were being carried out.

"Passengers were terrified," said Abdiwahab Hassan, an airport official.

Photographs show a large hole -- about a metre in diameter -- ripped in the side the plane just above the engines on the right wing, with streaks of soot on the plane.
