Eyewitnesses told the Yemen Post that dozens of armored vehicles, tanks, and hundreds of soldiers were sent to Aden province.
Military reinforcements have been deployed to Aden's districts in order to stop protesters from holding anti-government demonstrations.
This move came after the opposition parties the Joint Meeting Parties, JMP, called for the day of rage to be held in all Yemen's provinces on Tuesday.
Lately, Yemen's southern port of Aden has witnessed anti-government protests in which at least 12 protesters were killed and several others wounded after clashes were erupted between protesters and security forces.
