BEIRUT -- Russian or Syrian warplanes knocked a major Aleppo hospital out of service on Wednesday, hospital workers said, and ground forces intensified an assault on the city's besieged rebel sector, in a battle that has become a potentially decisive turning point in the civil war.
Shelling damaged at least another hospital and a bakery, killing six residents queuing up for bread under a siege that has trapped 250,000 people with food running out.
The World Health Organization said it had reports that both hospitals were now out of service.
