Syria's state-run news agency SANA says mortar attacks on the capital Damascus and its suburbs have killed five people and wounded 22.

Tuesday's attacks came hours before the new United Nations special envoy to Syria was scheduled to make his first visit to Damascus.

The U.N. said in a statement Monday that Staffan de Mistura and Deputy Envoy Ramzy Ezzedine Ramzy, who have assumed their functions in the beginning of the month, will travel to Damascus for consultations with Syrian officials on Tuesday.

SANA said two people were killed in Damascus and three in the suburb of Jaramana. It added that 15 were wounded in the shelling of Damascus and seven in Jaramana.
