It was one of the largest pro-government rallies in recent months, signalling that Gaddafi can still muster significant support.
A green cloth, several hundred meters long and held aloft by supporters, snaked above the crowd filling Tripoli's Green Square. Green is Libya's national colour.
A series of powerful explosions later rattled the heart of the capital, apparently new Nato airstrikes, as Gaddafi supporters cheered, honked horns and fired into the air in the street. Black smoke could be seen rising from the area near Gaddafi's Bab al-Aziziya compound.
Gaddafi spoke from an unknown location in a likely sign of concern over his safety. Addressing the West, he warned that Libyans might take revenge for Nato bombings.
"These people (the Libyans) are able to one day take this battle ... to Europe, to target your homes, offices, families, which would become legitimate military targets, like you have targeted our homes," he said.
"We can decide to treat you in a similar way," he said of the Europeans. "If we decide to, we are able to move to Europe like locusts, like bees. We advise you to retreat before you are dealt a disaster."
It was not immediately clear whether Gaddafi could make good on such threats.
