Libya's official government spokesman says 15 civilians were killed by a NATO airstrike on the home of one of Muammar Gaddafi' top officials in Surman, 70 kilometers west of Tripoli.
The attack came a day after NATO admitted killing civilians in a separate aerial attack.
This is the compound where Gaddafi's close aide Khouildi Hamidi was living.
It has been attacked by 8 NATO missiles.
The 68 year-old Hamidi and his wife were both in the house when the attack took place.
They were lucky to survive. However, Hamidi's 6 year-old grandson and 4 year-old granddaughter were killed.
The Libyan government said 15 civilians were killed.
Several civilian's homes were destroyed and an excavator worked to try and clear the heaps of rubble.
Government spokesman, Moussa Ibrahim condemned the attack, saying it targeted the civilians.
Moussa Ibrahim, Libyan Government Spokesman, said, "And I give you the logic.They want Libyans to give up the fight for fear that their families would be attacked and killed. "
Most of the injured people have been transferred to a hospital in nearby Sabrata.
Doctor, Sabrata Hospital, said, "Most of the victims were Sudanese living in Libya. The injured included Morocco nationals living in Surman and Sabrata."
NATO said it had bombed a legitimate military target, a command and control node in the area, and that it could not confirm whether civilians had been injured. It said NATO does its utmost to protect civilians.
If the Libyan government's account of civilian deaths is confirmed, the incident could further complicate the operations of the NATO-led military alliance. The operation is staring to feel the strain of a campaign taking longer and costing more than planned.
