Syrian opposition activists say clashes between rebels and government forces continue in the country's largest city, Aleppo, and in several other areas that have been key sites in the 16-month anti-government uprising.
The Britain-based Syrian Observatory for Human Rights reported shelling in several Aleppo neighborhoods Thursday that killed a girl and wounded seven other people.
It also said deadly clashes were taking place in the cities of Hama and in Deir Ezzor province, as well as explosions targeting military vehicles in Idlib.
Activists say the government has used attack helicopter and tanks during several days of fighting in Aleppo. White House spokesman Jay Carney said Wednesday those reported tactics are a sign of the depths of depravity of Syrian President Bashar al-Assad.
Also Wednesday, Arab diplomats said they are preparing to bring a Syria resolution to the United Nations General Assembly. The measure would likely mention Syria's statements earlier this week regarding the possible use of chemical weapons against foreign attackers.
U.N. General Assembly resolutions are non-binding and cannot be vetoed. Russia and China have vetoed three U.N. Security Council resolutions on Syria.
