A mosque containing Sufi Muslim graves has been bulldozed in the centre of Tripoli, Libya, a day after Sufi shrines in the city of Zlitan were wrecked and a mosque library was burned.

The demolition of the large Sha'ab mosque happened in broad daylight on Saturday, drawing condemnation from government officials and Libyans across the country and abroad.

Witnesses say a group of Salafi Muslims who disapprove of shrines and tombs were behind the attack, and that it took place as security forces looked on.
