One of Yemen's most influential political figures says President Ali Abdullah Saleh must leave the country, not just step down from power.
Hamid al-Ahmar, of the Islamist Islah party, told the BBC of opposition plans to escalate anti-government protests.
Hundreds of thousands of protesters took to the streets in several Yemeni cities on Wednesday.
Many also blame the government for blasts at an ammunitions factory on Monday that left 150 people dead.
