Two terrorist explosions rocked on Friday Syria’s second largest city of Aleppo, killing 28 people, including civilians, soldiers and children, and wounding 235 others.

The first explosion targeted a military intelligence center, while the second hit a center for security forces.

State TV aired footage of mangled bodies in pools of blood in the street outside a row of shattered buildings.

Several people interviewed by the channel denounced Turkey and Qatar for not standing by the regime in Syria.

A colonel in the so-called “Free Syrian Army” told France 24 earlier Friday that his group was behind the two blasts. However, Head of the FSA, Riad Al-Bashar later denied these allegations.

Friday's blasts were the biggest since two suicide bombings in the capital Damascus, one of which killed 44 people in December and the second 26 people in January.
