“The aid coming from outside is not enough. There is no hospital,” said the spokesman, who wanted to be identified only as “Mohammed” for safety reasons.

He said 21 people were killed and more than 100 were injured from shelling Sunday in Misrata. Monday’s shelling fell on the city’s critical port area — Misrata’s lifeline to humanitarian aid — and an industrial area that includes small businesses and small factories.

With a city hospital taken over by pro-government forces, makeshift clinics have popped up to treat the wounded. And in a city where access to food, water and electricity has been scarce, Mohammed said people have been using cell phones for light during surgery.
