Syrian officials say the government is considering a formal U.N. request to question six Syrian officers in connection with the killing of former Lebanese Prime Minister Rafik Hariri.
Officials say the request from chief U.N. investigator, German Prosecutor Detlev Mehlis, was handed over to the Syrian Foreign Ministry Sunday.
The officials did not identify the six wanted for questioning, or say if the United Nations wanted to conduct the questioning in Syria or outside.
Earlier, published reports in the Associated Press and the al-Hayat daily said that Syrian President Bashar al-Assad's brother-in-law General Assef Shawkat is among those wanted.
Last week, the United Nations Security Council unanimously adopted a resolution demanding Syria's cooperation with the U.N. probe, or face "further action."
