Blast at Israeli airline offices in Switzerland

An explosion has destroyed the entrance to the offices of the Israeli national airline El Al in the Swiss city of Zurich.

A group calling itself Revolutionary Perspective has claimed responsibility for the attack.

The explosion occurred shortly after midnight in one of the main shopping streets of the city. No one was injured.

The group, which has admitted three other attacks in the past year, said: "Stop the massacres in Turkey, Kurdistan and Palestine. Solidarity with the struggle of political prisoners."

It also called for "no more summits" such as the meetings in Seattle, Prague and Davos which provoked violent demonstrations from anti-globalisation activists.

The message said another attack had been carried out on the Turkish consulate in Zurich, but police said they had no knowledge of this.
