NATO attempts to bomb fear into defiant Qaddafi

As Muammar Qaddafi vows not to give up, NATO forces increase their bombing campaign.

On Wednesday, Qaddafi's forces resumed shelling Misrata, the city in western Libya held by rebels. At the same time, NATO kept pounding targets in Tripoli.

CBS News correspondent Allen Pizzey toured one of the bombed-out targets in Tripoli, and reports that some of NATO's targets seem strange, and perhaps telling.

Fifteen hours after what Libyan officials said was a missile strike, the smell of burning still hung in the air at one site. There were burnt boxer shorts, cell phone cases and camels all around. There was clear evidence that people lived there, but no reports of casualties.

What appears now to be a grazing place for camels, was apparently once much more. The fluttering windsock indicates there was a landing strip or helicopter pad nearby.

Libyan officials describe the bombing site as a nature park where important guests are often brought. However, after much prodding, they conceded that, yes, Qaddafi does spend time there.

Indeed the pieces of material CBS News found lying around look like nothing so much as the type of tent Qaddafi uses when he's playing his role of man of the desert.

The message from NATO to Qaddafi would seem to be: We know where you like to hang out.

Short of a "lucky strike," however, the reclusive Libyan leader is seemingly out of NATO's reach, but economic pressure is adding to a slow choking of the regime.

Only one land border crossing is open, and the naval blockade is effectively cutting imports of almost everything other than necessities.

The UN is warning of food shortages, and Libyans are growing weary of the bombing. Drivers in this major oil producer line up for days to fill their cars up. A recent UN mission measured one gas line that stretched for five miles.

Tankers that used to take out crude oil and bring in refined gasoline sit idle in port.

One item not in short supply are NATO bombs aimed at Qaddafi. While targeting his tent won't force him from the country, it does add to the places he can't sleep.
