Facilities unable to get supplies in or transport patients out left overwhelmed by incoming wounded

Patients with gunshot and shrapnel wounds have crammed into overwhelmed hospitals in Goma in the Democratic Republic of the Congo, many with serious injuries and in need of blood, after M23 rebels backed by Rwanda march into the city.

At least 2,900 people have been killed and thousands more wounded since the militia entered the city on 26 January, according to the UN. Fighting raged for the better part of last week.
