Islamic State lays explosives in Syria’s Palmyra ruins

Islamic State jihadis have mined the spectacular ancient ruins in Syria’s Palmyra, according to an antiquities official and monitor, prompting fears for the Unesco world heritage site a month after the extremist group overran the central Syrian city.

Syria’s antiquities chief, Maamoun Abdulkarim, and the Syrian Observatory for Human Rights monitor said on Sunday that the group had placed mines and explosives in Palmyra’s Greco-Roman ruins. The observatory, which relies on a network of sources on the ground, said the explosives were laid on Saturday.
