A NATO helicopter flies overhead Kabul International Airport, during an attack on the airport in Kabul July 17, 2014. Militants armed with rocket-propelled grenades attacked the airport on Thursday in one of the most audacious assaults on the facility, used by both civilians and the military, in a year. The airport is home to a major operational base for NATO-led forces that have been fighting insurgents for 12 years. REUTERS/Omar Sobhani (AFGHANISTAN - Tags: CIVIL UNREST TRANSPORT POLITICS) less
