Glasgow attack "terrorist incident": Scots minister

EDINBURGH (Reuters) - The attack at Glasgow's airport is being treated as a "terrorist incident", Scotland's First Minister Alex Salmond said on Saturday.

In the attack, witnesses said at least two men drove a four-by-four vehicle into the entrance of Glasgow's main terminal before the vehicle exploded in a ball of flames. No one was injured.

"Police are treating the attack as a terrorist incident," Salmond told reporters. "We are assessing the risk and taking appropriate levels of precaution."
