A double suicide bombing has rocked the center of the Syrian capital, Damascus.

The blasts, which according to the latest data, killed 14 people, happened in Marjeh Square, causing casualties, BBC News reported citing state-run television channel al-Ikhbariya.

In April, at least 13 people were killed in a blast, reported to have been caused by a car bomb, at the square.

The latest attacks come as regime forces prepare an assault to recapture the city of Aleppo from rebels.

Images on al-Ikhbariya showed a scene of widespread damage, with shop fronts blown out and debris littering the street. Blood stains marked the pavement, while people milled around among broken glass and wreckage.

The UK-based Syrian Observatory for Human Rights said the blasts had been caused by devices planted in the area, without giving further details.
