TRIPOLI, Libya – Cars sat abandoned in miles-long fuel lines, motorists traded angry screams with soldiers guarding gas stations, and many shops were closed Sunday on what should have been a work day.

In ever-multiplying ways, residents in the Libyan capital are feeling the sting of shortages from uprising-related disruptions of supplies.

The shortages are a dramatic sign of how Libya’s nearly 3-month-old rebellion is affecting daily life in Moammar Gadhafi’s stronghold and other western areas of Libya still under his rule.

International sanctions have begun to bite, many supply routes are unstable, and there are shortages of skilled people in some sectors to keep the city running smoothly.

Yet the deprivations pale in comparison to the situation in the port city of Misrata, the only rebel stronghold in western Libya. It has been under siege by land for two months, with hundreds of civilians killed, and Gadhafi’s forces are now trying to block access to the port that is Misrata’s only lifeline.

In Tripoli, the shortages were obvious, even to Western reporters who may only leave their hotel with a government minder and guard. Along the road linking Tripoli to Libya’s western border with Tunisia, long fuel lines were visible in a series of coastal towns.

Libyan-plated cars crowded gas stations in two small Tunisian towns close to the border, and a taxi driver there complained that shortages in Libya were driving up the price in Tunisia.

It is less clear what the eventual impact might be on Gadhafi’s ability to rule. An engineer based in Tripoli said Libyan TV blames the shortages on NATO, which is providing military muscle against Gadhafi, while average residents blame hardships on the regime.

The spokesman for the rebel administration in the eastern city of Benghazi, where there is no fuel shortage, blamed Tripoli’s shortages squarely on Gadhafi.

“He takes all the gasoline for his forces, and that is why there is none left for anyone else,” Abdel-Hafidh Ghoga told journalists.
