KUALA LUMPUR, Malaysia (AP) -- Malaysian police have fired tear gas and chemical-laced water at thousands of demonstrators demanding an overhaul in electoral policies.
At least 25,000 demonstrators have swamped Malaysia's largest city Saturday in one of the Southeast Asian nation's biggest street rallies in the past decade.
They massed near a public square that police had sealed off with barbed wire and barricades.
Some of the demonstrators apparently breached the barriers and police began firing tear gas at them.
The rally reflects concerns that Prime Minister Najib Razak's long-ruling coalition will have an unfair upper hand in elections that could be called as early as June.
