NATO strikes Tripoli overnight, 19 killed

NATO warplanes have pounded Tripoli for a second day, raising military pressure on Gaddafi's forces. At least six large explosions within 10 minutes of each other, rocked the Libyan capital.

The air strikes targeted the area around Gaddafi's Bab al-Aziziya compound. Libyan officials say the strikes killed 19 people. A NATO official says the alliance hit a vehicle storage bunker, a missile storage and maintenance site as well as a command-and-control site on the outskirts of Tripoli. Government targets around the Western rebel outpost of Misrata have also been hit.

Meanwhile, diplomatic activity in Libya is also increasing. South African President Jacob Zuma has announced he will visit Tripoli next week for talks with Gaddafi. G8 world powers will also discuss ways to break the impasse this week.
