Doctors in the Gaza Strip are donating their own blood to save their patients after scores of Palestinians were gunned down while trying to get food aid, the medical charity Doctors Without Borders (MSF) said on Thursday. Around 100 MSF staff protested outside the UN headquarters in Geneva against an aid distribution system in Gaza run by an Israeli-backed private company, which has led to chaotic scenes of mass carnage. "People need the basics of life...they also need it in dignity," MSF Switzerland's director general, Stephen Cornish, told Reuters at the protest.
