Turkish Prime Minister Recep Tayyip Erdogan has told US media he has evidence that Syria used chemical weapons against opposition forces.
He said that missile remains were discovered and Syrian patients showed signs of wounds from chemical weapons.
Similarly, US Secretary of State John Kerry said he now believed there was 'strong evidence' that Syria used gas.
Earlier on Friday, Erdogan said he believed Syria had crossed the red line 'a long time ago', the BBC reports.
He said Turkish intelligence had determined that the Syrian government had used at least 200 chemical missiles.
He did not give details on the type of chemical weapons he believed Syria had used, the report added. (ANI)
