A suicide bomber has launched an attack in the Syrian capital, with reports saying at least 7 people were killed.
Syrian police had been chasing three suspected car bombers that were trying to enter the capital, state TV said.
Police stopped and detonated two of the vehicles, but the third driver entered Tahrir square in the east and blew himself up after being surrounded.
At least 12 people were injured in Sunday's blast, reports said.
State TV said the attackers had planned to bomb crowded areas in the capital on the first working day after the Muslim holy month of Ramadan.
"The terrorist bombings killed and wounded several civilians and caused physical damage to the area," a police official told state news agency Sana.
