IS jihadists threaten ancient Palmyra ruins

The Islamic State group 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 expanded its control in Iraq. US President Barack Obama played down the developments, saying he didn't think the US was "losing" to IS.
