A bomb explosion rocked the heart of the Syrian capital on Wednesday, killing at least eight people and wounding 50 others, state media reported.
The blast came as rebels seized parts of a key arms depot in the central province of Homs and regime forces recaptured most of the Kurdish town of Tal-Aran in the northern province of Aleppo, a monitor said.
Also in Aleppo, fighters from the Al-Qaeda-affiliated Islamic State of Iraq and the Levant (ISIL) seized a major power plant, said the Syrian Observatory for Human Rights.
The blast in central Damascus hit Al-Hijaz Square, killing eight people including two women.
State news agency SANA said it was caused by a bomb placed at the entrance to the Hijaz railroad company and that more than 50 people had been wounded, among them women and children.
