Chanting "Sudan is rising, the army is rising," crowds of men and women massed outside the complex that also houses Bashir's official residence and the defense ministry, many of them having spent the night there, witnesses said, AFP reported.
"After what we did yesterday, we will not leave this area now until our mission is accomplished," said protester Osama Ahmed, who spent the night outside the compound.
"We won't leave this area until he steps down," he said, referring to Bashir.
Protesters whistled and waved at military vehicles entering the compound, prompting some soldiers to wave back, a day after demonstrators said they were gathering to ask the army to "come join us".
Riot police deployed near the complex Sunday morning, firing tear gas to disperse the crowds, a witness said.
Protest organizers chose April 6 to begin the rally outside the army headquarters to mark the 1985 uprising that toppled the then regime of president Ja’afar Nimeiri.
Ahead of the demonstration, organizers had urged the army to either "take the side of the people or the dictator's".
Chanting the movement's catch cry "freedom, peace, justice", thousands of men and women marched through the streets of the capital Saturday, reaching the fortified army complex for the first time since anti-government protests first broke out.
The rally was the biggest yet since protests erupted on December 19 in the central town of Atbara, quickly spreading to the capital and towns and cities across the country.
Rally organizers on Sunday urged the demonstrators to continue with their sit-in outside the army complex.
"We call on our people from areas near Khartoum to join those who are at the army headquarters," the organizers said in a statement.
Since the start of the protests, security agents and riot police have cracked down on demonstrators but the army has not intervened.
Witnesses said groups of women, men and children were walking towards the complex from several parts of the capital.
Several private companies declared a holiday at their offices, while some arranged to ferry water, snacks and juice to the protesters, according to witnesses.
In a separate demonstration on Saturday a protester was killed in Khartoum's twin city of Omdurman, police said.
Officials say 32 people have died since protests erupted in the east African country after a government decision to triple the price of bread.
Human Rights Watch has put the death toll to 51 including medics and children.
Rallies over bread prices quickly morphed into protests against Bashir's government, with demonstrators accusing it of mismanaging the economy, leading to soaring food prices and regular shortages of fuel and foreign currency.
Bashir has acknowledged that the economic concerns raised by protesters are "legitimate", but he imposed emergency rule on February 22 after an initial crackdown failed to rein in the protests.
The scale and intensity of protests have shrunk since the emergency rule went into effect.
But with Saturday's rally analysts say the protest movement has gained new momentum.
