In a message broadcast to residents of Tripoli, Libyan leader Moammar Gadhafi vowed to fight “until victory or death,” The Associated Press reported.

Gadhafi called on residents of the capital city to take up arms against the rebel forces and “free Tripoli.”

“Why are you letting them wreak havoc?” Gadhafi asked.

His message, which was broadcast from an undisclosed location on a local television station, came after opposition forces who entered Tripoli on Sunday overran his personal compound.

The Pentagon believes Gadhafi is probably hiding in the capital as his supporters continue to battle rebel forces in the city.

The White House continued to exert pressure on him to step down from power.

On vacation in Martha’s Vineyard, President Obama discussed the situation in Libya in a Tuesday phone call with French President Nicolas Sarkozy.

White House officials said Obama and Sarkozy repeated calls for Gadhafi to step down, and pledged to assist in the opposition’s leadership transition to a democratic government.
