Tourists were left terrified after they witnessed a man stab a stranger in the neck for no apparent reason at a busy Spanish airport.

Passengers at Palma airport in Mallorca watched on in horror as the frightening incident took place yesterday.

This attack is being described as a brutal assault without a motive.

Police said a man, with a companion, had gone to Son Sant Joan airport to pick up a friend who was flying into the island.

As he was waiting in the terminal, a man ran up to him and started to ask him something about his phone but he could not understand what he was saying.
