Russian President Dmitry Medvedev blamed airport management for "clear security breaches" (BBC) following a suicide bombing at Moscow's Domodedovo airport that left at least thirty-five dead. Medvedev ordered an investigation to establish if criminal negligence may have been involved, and suggested that more intense airport security based on U.S. and Israeli procedures be instituted. Russian investigators suspect militants from the North Caucasus (DeutscheWelle), a primarily Muslim region, in the planning and execution of the attack. Analysts say the attacker profiles are reminiscent of the so-called "black widow" assailants (Guardian), two women from the North Caucasus believed responsible for a similar attack in Moscow in March 2010. Over the past ten years, bombers have hit transportation (CNN) operating in and out of Moscow at least four times, with a combined death toll of more than one hundred victims.

Analysis:

This article for The Daily Beast suggests recent security crackdowns instigated by Vladimir Putin have not made Russia safer from terrorist attacks.

This piece from the Periscope Post asks "Who is really to blame for the Moscow Airport bombing?"

Background:

Russia has been targeted repeatedly over the past decade by suicide bombings and other strikes. The Washington Post provides a partial list of major attacks.

New screening measures at U.S. airports are being called overly intrusive by some passengers and civil rights groups. National security experts advise using a system that relies more on intelligence, behavioral profiling, and empowering passengers.
