The Libyan government promised death to "invaders" in the country after saying one of ruler Moammar Gadhafi's sons -- Saif al-Arab Gadhafi -- was killed in a NATO airstrike.
Moammar Gadhafi and his wife were in their son's house when it was targeted, spokesman Musa Ibrahim told journalists Sunday. Both of them were in good health, according to the spokesman.
Saif al-Arab Gadhafi is one of two Gadhafi sons whose names begin with Saif. The other is Saif al-Islam Gadhafi, who had previously touted reform but has emerged as one of his father's most visible defenders in recent months.
Ibrahim said three of Moammar Gadhafi's grandchildren also died in the attack.
Ibrahim railed against NATO after the strike, calling it an illegal act and a "war crime." ****
