Huge crowds have poured onto the streets of the Yemeni capital Sanaa in what the opposition hailed as the biggest protest yet against President Ali Abdullah Saleh's three-decade rule.
Saleh's opponents massed in streets leading to a square near Sanaa University, where students and pro-democracy demonstrators have been camped for more than a week.
The demonstration came as Saleh accused Israel of financing and plotting the protests in his country and other Arab states, and criticized U.S. President Barack Obama for expressing support for the protesters.
Saleh, a key U.S. ally in the fight against terrorism, is under mounting pressure by daily protests demanding an end to his 32-year-old rule.
UN High Commissioner Navi Pillay warned the authorities in Sanaa against using violence to repress the protests.
