In a statement, the Hezbollah Brigades said the message of the Iraqi people’s million-strong epic reached the world, almaalomah.com reported.
It said the Iraqi nation’s clear message was that the land of Mesopotamia is no place for occupiers.
All the world heard the message, it went on to say.
People rallied in Baghdad in massive numbers to call for an end to US military presence in Iraq following high-profile assassinations and airstrikes targeting anti-terror forces.
Sayed Sadiq al-Hashemi, the director of the Iraqi Center for Studies, said more than 2.5 million took part in the demonstrations on Friday.
Since the early hours on Friday, huge crowds of men, women and children of all ages converged on the Jadriyah neighborhood near Baghdad University.
The protesters were seen carrying banners and chanting slogans calling for the expulsion of US forces.
“Get out, get out, occupier!” some shouted, while others chanted, “Yes to sovereignty!”
Iraq’s al-Ahd news network reported that Iraqis from all of the country's provinces had gathered in the city.
On January 5, the Iraqi parliament voted overwhelmingly in favor of a resolution calling for the expulsion of all foreign forces after the US assassination of Iran's General Qassem Soleimani and his Iraqi trenchmate Abu Mahdi al-Muhandis.
The massive rally came after influential cleric Muqtada al-Sadr called on Iraqis to stage "a million-strong, peaceful, unified demonstration to condemn the American presence and its violations".
Sadr issued a statement on Friday calling for US bases to be shut down and Iraqi airspace closed to US warplanes and surveillance aircraft.
He warned that US presence in the country will be dealt with as an occupying force if Washington does not agree with Iraqi demands to withdraw for the country.
