BEIRUT - A section of the wall of the ancient citadel in Aleppo was destroyed by an explosion in a tunnel under the city, state media and activists reported on Sunday.
The Syrian Observatory for Human Rights said the damage occurred when government forces blew up a tunnel dug by insurgents under the city, while the state news agency said the tunnel was blown up by rebels.
A section of the wall was shown turned to rubble in footage posted online by Halab News Network, an activist outlet.
