WOODBURY - Deep cracks opened in Moammar Gadhafi's regime today, with Libyan government officials at home and abroad resigning, air force pilots defecting and a major government building ablaze after clashes in the capital of Tripoli. Protesters called for another night of defiance against the Arab world's longest-serving leader despite a crackdown.

Rep. Peter King (R-Seaford) says most Libyans want Moammar Gadhafi to step down. But King, who is also the head of the House Homeland Security Committee, says he's concerned about who might take over if Gadhafi is ousted.

"It's great to see a tyrant ? be overthrown, but the successor could be worse and could have a long-term impact on us," King says.

Experts say gas prices could go up to $4 a gallon by spring, especially if the political unrest spreads to Saudi Arabia.
