Explosion in Aleppo 'kills 17'
At least 17 people have been killed by a car bomb in Syria's largest city, Aleppo, state news agency Sana says.
Syrian state TV said two hospitals and a school were largely destroyed by the blast near the city sports stadium.
The Free Syrian Army said it carried out the attack because the facilities were being used by government troops. Earlier, a strike killed at least five people, witnesses said.
