More civilians have died in political unrest in Yemen's capital Sanaa, a day after 26 people were shot dead at a rally in the city.
Witnesses said security forces once again opened fire on protesters, who had promised to carry on their campaign to oust President Ali Abdullah Saleh.
Reports said at least two people had been killed in the latest violence.
The government denied carrying out Sunday's killings, blaming Islamist groups for firing on the rally.
But witnesses and protesters dismissed the government's account.
For months, thousands of people have been waging a campaign to depose Mr Saleh, who is currently in Saudi Arabia recovering from a bomb attack in June.
