The British government has just raised the terrorism alert level for that country to "Critical", the highest alert level.
GLASGOW, Scotland – Two men rammed a flaming Jeep Cherokee into the main terminal of Glasgow airport Saturday, crashing into the glass doors at the entrance in what appeared to be the third attempted terror attack on Britain in two days, witnesses said.
Hours later, Britain raised its security alert to "critical" — the highest level possible and an indication that terrorist attacks are imminent. U.S. airports increased safety precautions.
Both suspects were arrested at the Glasgow airport, Scotland's largest. One, his body engulfed in flames as police pulled him from the vehicle, was hospitalized.
Obviously, they believe they have a real problem right now. After three attempts in the past day or so, they appear to be correct.
