Over the weekend, violence in the city of Aleppo, Syria, continued to claim lives.
It also claimed a piece of Syria's cultural heritage, its centuries-old covered market.
Hundreds of shops were destroyed by fire in the souk, which UNESCO recognizes as a World Heritage Site.
Amr Al-Azm, teaches Middle Eastern History and Anthropology at Shawnee State University in Ohio.
He says the medieval architecture of this market had been exceptionally well preserved.
