South Africa: Mandela's 90th

QUNU — Nelson Mandela sat beaming in a yellow armchair, his legs propped up on a large stool and covered with a pale yellow blanket. Ten grandchildren crowded around to serenade him with "Happy Birthday" and then smothered him with hugs and kisses.

The anti-apartheid icon celebrated his 90th birthday Friday with his family at his home in rural southeastern South Africa, and the whole village turned out. Sounding and looking vigorous, Mandela told a small group of reporters he was fortunate to have reached 90, crediting his "behavior" for his longevity.

Colombia: March for hostages

BOGOTA — Tens of thousands are expected to join marches across this nation Sunday, which will be joined by simultaneous gatherings in South Florida, Paris and other cities around the world, to demand the release of hundreds of hostages still held by leftist rebels in the jungles and mountains of Colombia.

Mexico: U.S. aids in drug bust

MEXICO CITY — Homeland Security Secretary Michael Chertoff said Friday that U.S. intelligence led Mexican forces to a small submarine captured this week packed with 5.8 tons of cocaine.

Chertoff called the vessel's seizure Wednesday off Oaxaca state in southern Mexico "a great example of our cooperation." Mexican navy Vice Adm. Jose Maria Ortegon said the 30-foot green submarine was equipped with GPS and a compass, and its crew had planned to drop off its shipment on Mexican shores. Authorities arrested four Colombian crew members who claim to be fishermen forced by drug cartels to move the cargo.

United Nations: New chief

UNITED NATIONS — The United Nations chief told rights advocates Friday that his choice to be the next U.N. human rights commissioner is a South African judge who was the first black woman to serve on her country's high court, the director of Human Rights Watch said.

Secretary-General Ban Ki-moon said he had selected Navanethem Pillay for the job, but he had not yet taken official action, said Kenneth Roth, who was among a dozen representatives from human rights groups who met with Ban. Ban's office is expected to announce her appointment early next week.
