TRIPOLI, Libya (AP) — Fierce fighting erupted around Moammar Gadhafi's main military compound in Tripoli on Tuesday, hours after the Libyan leader's son and heir apparent turned up free to thwart Libyan rebel claims he had been captured and rally supporters.
The surprise appearance of Seif al-Islam energized regime loyalists and underlined the potential for Gadhafi to strike back even as his grip on power seemed to be slipping fast.
Kirsan Ilyumzhinov, the Russian head of the World Chess Federation who has known Gadhafi for year, also said he spoke Tuesday by telephone with Gadhafi and the Libyan leader remains in Tripoli.
Ilyumzhinov, who was received by Gadhafi in Libya in July, said in an interview with the Interfax news agency that Gadhafi called him at around 6 p.m. Moscow time (1400 GMT, 10 a.m. EDT) on Tuesday and told him that he was "alive and well and still in Tripoli."
The report couldn't be independently confirmed.
Street battles between pro-Gadhafi troops and rebels broke out in several parts of the city, and the mood turned from one of euphoria to confusion and fear a day after opposition fighters swept into the capital with relative ease, claiming to have most of it under their control.
Thick clouds of gray and white smoke filled the Tripoli sky as heavy gunfire and explosions shook several districts of the city of 2 million people.
NATO warned the situation in Tripoli remains very dangerous and promised the alliance will continue bombing forces loyal to the 69-year-old Libyan leader if they keep fighting.
"Snipers, shelling, missiles could do much damage, but they can't change the course of history or the outcome of this campaign," spokesman Col. Roland Lavoie told reporters at a news conference in Naples, Italy. He said NATO had to stay vigilant because of fluidity of the situation on the ground.
"Most notably, Tripoli is still the site of numerous clashes between pro- and anti-Qadhafi forces, and the tension is far from being over. The situation in Tripoli is indeed very, very dynamic and complex, even today, and we are closely monitoring developments hour after hour," he said.
Some of the heaviest fighting Tuesday was around Gadhafi's Bab al-Aziziya main compound and military barracks, with both sides battling it out with heavy machine-guns, mortars and anti-aircraft guns. The sprawling complex, heavily damaged by NATO airstrikes, emerged as one of the centers of government resistance since tanks rolled out Monday and fired at rebels trying to get in.
Associated Press reporters at the scene said the two sides were positioned across either end of an empty field outside the complex on Tuesday. The fighting continued until early evening with columns of smoke rising from the site.
NATO officials in Brussels said the alliance's warplanes were flying over Tripoli on Tuesday, but that there have been no bombing runs.
The ferocity of the fighting over the compound led to speculation that Gadhafi or members of his immediate family may be sheltering there. But Gadhafi's former right-hand man Abdel-Salam Jalloud told Al-Jazeera television that he thought the Libyan leader was moving around the outskirts of Tripoli, taking shelter at private homes, small hotels and mosques. Jalloud defected this month.
However, a senior rebel official, Ahmed Jebril, said that Gadhafi was believed to be at Bab al-Aziziya. "He was taken by surprise. He never expected the speed by which fighters have taken over Tripoli or the collapse of his forces. It was too quick. He was not prepared to leave Tripoli," he told The Associated Press by telephone from Benghazi, the de facto rebels' capital in eastern Libya.
"We don't know who is inside Bab al-Aziziya. We believe that there is someone there and that he is leading a fierce battle. It is a symbol. This is the final castle of Gadhafi," said Mahmoud Shamman, a Doha-base spokesman for the rebels' interim council.
The standoff over Bab al-Aziziya occurred after Seif al-Islam, with a full beard and wearing an olive-green T-shirt and camouflage trousers, took a group of foreign journalists to the area as part of a tour aimed at showing the regime still has support. At Bab al-Aziziya, at least a hundred men were waiting in lines for guns being distributed to volunteers to defend the regime. Seif al-Islam shook hands with supporters, beaming and flashing the "V'' for victory sign.
"We are here. This is our country. This is our people, and we live here, and we die here," he told AP Television News. "And we are going to win, because the people are with us. That's why were are going to win. Look at them — look at them, in the streets, everywhere!"
It was not clear whether Gadhafi's son, who turned up at the Rixos hotel, where about 30 foreign journalists have been staying under the close watch of regime minders, had escaped from rebel custody or never been captured in the first place.
