The Syrian government asked UN Secretary-General Ban Ki-moon on Wednesday to appoint an independent mission to investigate an alleged chemical weapons attack by rebels in northern Syria.

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

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