DIA Operations Normal After Belgium Attack

DENVER (CBS4)- Operations at Denver International Airport are normal after the deadly terror attack in Belgium.

DIA spokesman Heath Montgomery told CBS4 that TSA has not directed them to do anything different. He also said as a major international airport, DIA always has a heightened sense of awareness.

The Islamic State group has claimed responsibility for the attacks in Brussels, saying its extremists opened fire in the airport and "several of them" detonated suicide belts. The posting by the group's news agency says another suicide attacker detonated in the metro. The posting said the attack was in response to Belgium's support of the international coalition arrayed against it.

The bombs at the airport and a metro station killed at least 31 people and wounded dozens of others. It happened just days after the key fugitive from last year's Paris attacks was arrested in Brussels.

American Airlines, Delta and United Airlines all said that their flights to and from Brussels were either cancelled or diverted.

Security was tightened across Europe, just four months after coordinated attacks in Paris killed 130 people.
