Syria asks UN chief to appoint independent mission to investigate alleged chemical attack

Syria has asked the U.N. secretary-general to appoint an independent technical mission to investigate an alleged chemical weapons attack by rebels in the country's north.

Rebels in northern Syria deny the government claim and blamed regime forces for Tuesday's missile attack on Khan al-Assad village in northern Aleppo province.

Syria's U.N. Ambassador Bashar Ja'afari told reporters Wednesday morning that he had just asked Secretary-General Ban Ki-moon "to form a specialized, independent and neutral technical mission to investigate the use by the terrorist groups operating in Syria of chemical weapons yesterday against civilians in the town of Khan al-Assad in Aleppo."

The U.S. ambassador to Syria said Wednesday the Obama administration has no evidence to support Syria's claims.

Ja'afari stressed his government has repeatedly said it would never use chemical weapons.
