Yemenis demand president's removal

Several members of the Yemeni president’s ruling Congress party have resigned as tens of thousands of people again took to the streets to demand his removal.

President Ali Abdullah Saleh, a key US ally in fighting an al Qaida offshoot in his country, refuses to budge and rejected a proposal from a coalition of opposition groups to end the political stand-off by agreeing to step down by the end of the year.
