An Afghan security official says at least 400 fuel tankers caught fire late Friday night in a parking lot in the outskirts of Kabul, AP reported.
Hashmat Stanikzai, spokesman for Kabul's police chief, on Saturday said police were investigating the cause of the fire, which continues to burn.
Stanikzai says there are fears of casualties.
Taliban spokesman Zabihullah Mujahid has claimed responsibility for the attack. His statement sent to the media says the Taliban set fire to foreign forces' fuel tanker supplies in a tactical attack.
