US authorities are considering ways to tighten security in public areas at US airports after a deadly attack in Moscow last month, John Pistole, the head of the US Transportation Security Administration, said on Thursday.
A suicide bomber last month killed 36 people and injured more than 100 after detonating the device in the international arrivals hall of Moscow's busy Domodedovo airport, sending airport officials scrambling to address the security gap. (Reuters)
