ANKARA- Turkey said on Friday any use of chemical weapons by Syrian President Bashar Assad would "take the crisis to another level", but remained cautious about any foreign military intervention in the conflict on its border.
The White House said on Thursday Assad's government had probably used chemical arms on a small scale, but that President Barack Obama needed proof before he would act.
"We have been hearing allegations of the use of chemical weapons for quite some time now and these new findings take things to another level. They are very alarming," Turkish foreign ministry spokesman Levent Gumrukcu said.
"Since the very first reports of chemical weapons being used in Syria emerged we have been asking for a thorough investigation by the United Nations to substantiate these reports. However, the Syrian regime has not allowed this."
