BERN, Switzerland (AP) — A rock star welcome greeted Aung San Suu Kyi as she embarked on her first trip to Europe in 24 years. But after a whirlwind of standing ovations, speeches and receptions, it all became too much, and she fell ill Thursday during a news conference in Switzerland.

The 66-year-old Nobel Peace Prize laureate became sick shortly after saying how exhausted she was after her long trip from Asia to Europe, which brought her to Geneva late Wednesday night. It was not known how her apparent exhaustion would affect the rest of a tightly-packed schedule, which includes delivering her Nobel Peace Prize acceptance speech in Oslo on Saturday, 21 years after winning the award.
