KABUL, Jan. 10 (Xinhua) -- Two explosions ripped near a government office along a busy road in the western part of the Afghan capital Kabul on Tuesday, leaving casualties, witnesses and sources said.
"The first blast came after a suicide bomber detonated his explosive jacket near a government employees' bus at around 3:45 p.m. (local time). The second blast came 10 minutes later," witness Mohammad Safa said.
The attacks resulted in unknown casualties. The nature of the second blast was like a car bombing, he said.
Thick black smoke was seen billowing from the site after the second blast.
The attackers seemed to have followed old tactics which created an initial blast to attract security forces and people and then set off another blast to cause high casualties.
Security forces have cordoned off the area for precautionary measures.
