ALMATY - Kazakhstan arrested and jailed two top opposition leaders on Saturday as hundreds of protesters braved thrice as many police to rally against strongman President Nursultan Nazarbayev’s rule. Nearly 1,000 people gathered on the main Palace of the Republic square in the financial capital Almaty to express outrage at the energy-rich state’s rights record under the veteran leader. Police raided the homes of three leaders of the unregistered Azat (Freedom) party before the event began and hauled them off to a central police station for questioning, a party spokesman said by telephone.
