AMMAN (Reuters) - Syrian warplanes bombarded the city of Raqqa on Tuesday, a day after it was captured by rebel fighters, opposition campaigners and a resident said.

"The center of the city is being bombarded by warplanes. I counted 60 rockets," the resident said, adding that hospitals had issued calls to donate blood as casualties mounted.
