(Thomson Reuters Foundation) – Late last year, a bunker buster bomb shot through an underground shelter in Syria’s Hama province. A group of aid workers were taking shelter inside at the time. Nine of them, all Syrian, were killed instantly. In February, six Red Cross workers were shot dead in an ambush in northern Afghanistan while travelling through the desert to deliver livestock supplies to people in need. Their vehicles were clearly marked as humanitarian. The International Committee of the Red Cross described the incident as the worst attack against them in 20 years.
