TRANSITION UNCLEAR AFTER PM'S OUSTER

YEREVAN, ARMENIA The abrupt resignation of Armenian Prime Minister Serzh Sargsyan after two weeks of protests against his rule has caught the opposition off guard: The protesters had focused on driving out what they consider a corrupt elite, and seem to lack the structure or the political platform to replace it.

The protests, which lasted 10 days, culminated on Monday when Sargsyan, who has ruled Armenia since 2008, announced his resignation.

The opposition wants acting prime minister Karen Karapetian, an ally of Sargsyan, to also step down. But it appears far from ready to form a united political force.
