Syria crisis: Huge blast 'destroys Aleppo hotel'
A large explosion in the northern Syrian city of Aleppo has destroyed a hotel and several other buildings, state media and activists report.
Rebel fighters are believed to have detonated a bomb placed in a tunnel beneath the Carlton Citadel Hotel, near the city's medieval citadel and souk.
But the BBC's Paul Wood says the hotel itself may not have been the intended target.
