Austria will provide Switzerland with air defense support to prevent terrorist attacks on this year's World Economic Forum annual meeting in Davos, the Austria Press Agency (APA) reported Tuesday.

The Austrian air force will move several warplanes, hundreds of troops and radar equipment from central Austria to boost air defense in the west of the country for the five-day event, said the APA.

Davos lies only 15 km from the Austrian border.

The Austrian military said Tuesday that air defense cooperation between the two countries is necessary for quick response to possible terrorist attacks on the Davos event.

A "no-fly zone" will be established for the meeting. The Austrian air defense system can detect any suspicious flying objects and react properly, said the military.

Austrian warplanes may also have to cross the border for certain missions, it added.

The Davos meeting in the following five days is expected to attract 2,250 delegates from 96 countries and territories, among them more than 20 heads of state or government.
