Police probe hotel blast in Davos
A small blast has broken windows at a hotel close to the site of the World Economic Forum in Davos, Switzerland.
Police spokesman Thomas Hobi said nobody was injured in the blast, which happened in a storage room at the Posthotel Morosani. Police are investigating the incident.
The hotel is just over a mile from the main venue of the annual gathering in the Alpine ski resort of Davos.
A forum-related lunch focusing on organised crime, called Criminals Without Borders, was scheduled for the hotel at noon on Thursday, with speakers including Colombian president Juan Manuel Santos and Robert Wainwright, the director of Europol, or European Police.
There is tight security at the World Economic Forum as left-wing groups plan to hold a protest this weekend against the annual meeting of political and business leaders.
Anonymous leaflets circulated at a demonstration last week in the north-eastern Swiss town of St Gallen urged activists to "Smash (the) WEF".
The leaflet said: "Let us fight together against the unbearable propaganda of capitalism."
In previous years violent activists have stayed away from the resort and staged violent demonstrations elsewhere in Switzerland.
The Forum said in a statement a firework in the back of the hotel was to blame. The hotel did not comment.
