Islamic State group jihadists seized Syria's Palmyra on Thursday, as UNESCO warned that the destruction of the ancient city would be "an enormous loss to humanity". The capture of Palmyra, a 2,000-year-old metropolis, reportedly leaves more than half of Syria under IS control and comes days after the group also expanded its control in Iraq.
