Kenya's parliament has reopened, with President Mwai Kibaki urging lawmakers to enact power-sharing legislation agreed to with his challenger in December's election, Raila Odinga.

Northern Ireland's Protestant and Catholic political leaders have until the end of the day Monday to restart a power-sharing executive, or Britain will dissolve the government.
