"According to the information we have there are three dead and 150 wounded," he told journalists on a bus taking them to a hospital shortly after the strikes.
Ibrahim said NATO had carried out "between 12 and 18 raids on a barracks of the people`s guard", volunteer units who back up the army.
Most of the victims were civilians living nearby, the spokesman added.
An AFP journalist said the raids lasting more than half an hour began at around 1:00 am (2300 GMT Monday) when powerful blasts were heard in the sector around leader Moamer Kadhafi`s Bab al-Aziziya residence.
They were preceded by a whistling noise and the formation of red balls in the sky, a witness said.
More than 15 strong blasts were heard in the neighbourhood, with the sound of warplanes roaring overhead.
It was the most intense raid since the start of NATO operations against Kadhafi`s regime.
The Bab al-Aziziya sector has already been targeted several times by NATO aircraft.
Tripoli is targeted nearly daily with air raids by the international coalition, which launched strikes on March 19 to prevent strongman Kadhafi`s forces from attacking civilians.
NATO took over command of the operation on March 31. (*)
