* Biggest protest in days in Tunisia capital
* Protestors call for Libya's Gaddafi to step down
* Many also call for changes to Tunisia interim gov't
TUNIS, Feb 25 (Reuters) - Thousands of people filled the streets of central Tunis on Friday shouting slogans and carrying placards in a "day of rage" against Muammar Gaddafi's crackdown in neighbouring Libya.
Gaddafi loyalists have killed scores of protesters in the North African oil exporter country who, inspired by Tunisia's revolution last month and a similar revolution in Egypt, have called for him to step down.
The protesters shouted "Gaddafi out!" and a witness said the demonstrators had dubbed the demonstration -- the biggest in the capital in almost a week -- their "day of rage".
Many of the protesters were also calling for the resignation of former regime loyalists, including Prime Minister Mohamed Ghannouchi, from Tunisia's interim government.
The caretaker government charged with setting presidential and legislative elections in the coming months has already undergone several changes after street protests.
Military helicopters circled overhead while security forces eyed the crowd, which formed in defiance of a government ban on demonstrations since Tunisia's revolution toppled Zine al-Abidine Ben Ali on Jan. 14.
Thousands of people have been streaming across Tunisia's border from Libya to escape the violence there in recent days, many telling of roving gangs of armed Gaddafi loyalists, and of abuses by police targeting Tunisians and Egyptians.
Libya's government, facing mounting international condemnation since the revolt, has ordered cash handouts include wage increases, food subsidies and allowances, Libyan state television reported.
