According to CNN (Europe), a Red Cross worker tried to bring in supplied to the navy headquarters in Crimea. Probably, this aid was intended for the military of Ukraine in Crimea.
"The men blocking the navy headquarters entrance turned away a Sevastopol Red Cross worker who tried to bring in supplies.", http://edition.cnn.com/2014/03/05/world/europe/ukraine-crimea-local-color/
Is it legal for the Red Cross and other aid organisations to give aid to belligerent forces or non-civilians in a conflict such as this? And if so, is it their policy to give such aid?
