TRIPOLI, Libya — Longtime Libyan dictator Moammar Gadhafi has been killed, interim Prime Minister Mahmoud Jibril said Thursday.

The confirmation came after hours of conflicting reports about the former leader’s status.

Gadhafi’s son, Mutassim, and his chief of intelligence, Abdullah al-Senussi, were also killed, said Anees al-Sharif, a spokesman for the Tripoli military council.

Revolutionary fighters attacked the house where Gadhafi was hiding, said Information Minister Mahmoud Shammam. Gadhafi was shot while trying to flee, he said.

“Colonel Gadhafi is history,” he said.

A grisly cell phone video aired on Al-Jazeera Arabic showed a bloodied Gadhafi with a wound to his head. A cell phone photograph distributed by the news agency Agence France Presse also appeared to show Gadhafi severely wounded. CNN could not independently verify the authenticity of the images.

U.S. Secretary of State Hillary Clinton, who visited Tripoli this week, could not confirm Gadhafi’s capture or killing but said it would “add legitimacy and relief to the formation of a new government.”

Abubaker Saad, who served as a Gadhafi aide for nine years, said it didn’t really matter whether Gadhafi was dead or alive — as long as he was no longer a fugitive.

“As long as he was on the run he represented a very ominous danger to the Libyan people,” Saad said. “He represented a very ominous danger … to the idea of the democracy in Libya.”

Saad said he never saw Gadhafi sleep in the same place two nights in a row.

“This man has been doing it for 42 years. He has experience in hiding,” Saad said. “So, I am thrilled to see the Libyan fighters in Sirte (were) able to kill him or capture him.”

In another major development, revolutionary fighters said they wrested control of Sirte on Thursday. NATO said it is going to convene soon for a meeting to discuss ending its operation in Libya, a source told CNN.

Earlier, NATO aircraft struck two pro-Gadhafi military vehicles in the Sirte vicinity.

Libyans, who have been waiting for months for Gadhafi’s demise, erupted in deafening celebrations.

Horns blared and celebratory gunfire burst into the air in Tripoli.

Gadhafi ruled Libya with an iron fist for 42 years. The mercurial leader came to power in a bloodless coup against King Idris in 1969, when he was just an army captain.

By the end of his rule, he claimed to be “King of Kings,” a title he had a gathering of tribal leaders grant him in 2008.

But a February uprising evolved into civil war that resulted in ousting the strongman from power.

Earlier, anti-Gadhafi fighters said they had taken control of the last holdout of loyalists in Sirte. They said they were still battling pockets of resistance, but they were in control of District 2.

Sirte has been the big prize for Libya’s NTC, waiting for the city to fall to officially declare liberation.

Most residents abandoned Sirte in the many weeks of bloody battles that raged there. Revolutionary forces have fought Gadhafi’s men street by street, cornering the last vestiges of the old regime to that last district.

Gadhafi, wanted by the International Criminal Court in The Hague, Netherlands, for alleged crimes against humanity, had not been seen in public in months.
