By Trinna Leong and Al-Zaquan Amer Hamzah KUALA LUMPUR (Reuters) - Thousands of protesters gathered in Kuala Lumpur on Saturday for a two-day rally to demand the resignation of Prime Minister Najib Razak, bringing to the streets a political crisis over a multi-million-dollar payment made to an account under his name. Protesters hope to spark a people's power movement forcing Najib out, but political analysts doubt he will be toppled. Security was tight as the rally got under way and access to a square where the protesters plan to converge was blocked.
Usain Bolt will have the chance to go for a golden treble at the world championships in Beijing after his teammates advanced into the finals of the 4x100m relay on Saturday. A Jamaican quartet comprising Nesta Carter, Asafa Powell, Rasheed Dwyer and Nickel Ashmeade clocked a season's best of 37.41 seconds -- the 10th fastest time ever run -- to win their heat ahead of France and China, whose 37.92 was an Asian record. It means Bolt, who has already beaten American rival Justin Gatlin to the 100 and 200m titles, will have the opportunity to return home with a third world gold from Beijing when he replaces one of his teammates for the final.
