Relations between Libya and Switzerland have taken a turn for the worse.
Libyan leader Muammar Gaddafi has called for a jihad or holy war against the Alpine country. He claims Switzerland is destroying mosques.
In November a majority of Swiss nationals voted in favour of a ban on the construction of minarets.
However, the Government in Bern urged voters to reject the ban. It warned that it would contravene religious freedom.
Speaking on the birthday of Mohammed, Gaddafi said masses of Muslims must stop Swiss aircraft landing at airports in the Islamic world, as well as Swiss ships docking and Swiss goods being sold.
Libya’s relations with Switzerland broke down in 2008 when a son of Gaddafi was arrested in a Geneva hotel and charged with abusing domestic servants. He was released shortly afterwards.
Libya has freed one of two Swiss nationals who had been sheltering in the Swiss embassy in Tripoli.
The other has started a four month sentence for immigration violations.
