World powers reacted with outrage on Friday at a call by Colonel Gaddafi of Libya for holy war on the "obscene, infidel" state of Switzerland.

Col Gaddafi took a long-running and personal feud with the historically neutral European country to new heights with a speech in which he attacked the ban on new minarets on mosques approved by a Swiss referendum last year.

"Those who destroy God's mosques deserve to be attacked through jihad, and if Switzerland was on our borders, we would fight it," he said. "Jihad against Switzerland, against Zionism, against foreign aggression is not terrorism."

He called for a boycott of Switzerland by the Islamic world. "Any Muslim in any part of the world who works with Switzerland is an apostate, is against Mohammad, God and the Koran," he said.

"The masses of Muslims must go to all airports in the Islamic world and prevent any Swiss plane landing, to all harbours and prevent any Swiss ships docking, inspect all shops and markets to stop any Swiss goods being sold."
