In addition to the 100 people said to have been killed in Homs on Wednesday, there are also believed to be around 200 wounded.
Treating the injuries is a big problem, with reports from residents that snipers are shooting at people trying to deliver food and medical supplies.
Medical aid agency Medecins Sans Frontieres claim the Syrian regime is persecuting doctors and health workers treating wounded demonstrators and denying medical care to opponents.
The organisation still has not been allowed to work inside Syria, but says it is helping those who have escaped to neighbouring countries.
It seems the people of Homs are improvising when it comes to looking after the wounded with makeshift hospitals in houses and other buildings.
Medical equipment remains scarce and people accuse the government of actually targeting hospitals.
