At least five people, including two minors, have been killed in a collision between a helicopter and a light plane on the Spanish island of Mallorca.

The Balearic Islands government said on Twitter that the accident happened at 1.35pm in the town of Inca.

It was not known what caused the collision between the aircraft.

Local newspaper Diario de Mallorca report both of them were privately used. 

Two Spanish citizens were on board the ultralight plane and three adults and two minors, believed to be German nationals, were in the helicopter.

Spanish acting Prime Minister Pedro Sanchez expressed his condolences on Twitter saying: "My solidarity and love for the families of the victims that lost their lives in this tragic accident."
