The Austrian site where AC/DC is supposed to do a concert may have unexploded World War II bombs, government officials have warned.

The authorities are concerned about the safety of 80,000 people who may come to watch the rockers perform at Wels Airport on 22 May.

The airport had apparently been the target of heavy bombing during the war, reports the Daily Express.

Wels' deputy mayor Hermann Wimmer revealed that bomb defusing and de-mining experts would check the site and present their reports before the gig gets the nod. (ANI)
