TEHRAN, Jan. 13 (Xinhua) -- Tehran's police chief Hossein Rahimi on Monday denied that the security forces under police commandment had shot at the protesters over the past few days, state TV reported.

On Saturday and Sunday, hundreds of people tried to stage demonstrations in the capital Tehran in protest against the downing of a Ukrainian passenger plane by Iran's Islamic Revolution Guards Corps (IRGC) over Tehran's airspace.

The IRGC accepted the responsibility for "mistakenly" shooting at the plane, blaming it on "human error."

Rahimi said that the Tehran's police officers have been ordered to show restraint in the face of protests.
