HARARE, Zimbabwe -- Zimbabwe's incoming leader Emmerson Mnangagwa has been sworn in, beginning a new era for the long-troubled nation. He promises to devote himself to the well-being of the people, to cheers from tens of thousands present.

He succeeds Robert Mugabe, who resigned on Tuesday under immense pressure from the military, the ruling party and the people amid fears his wife was trying to take power.

Mnangagwa was Mugabe's longtime ally before his firing earlier this month. He will serve until the end of the presidential term next year. An election date has not yet been set. (AP)
