KUALA LUMPUR (Reuters) - Malaysian opposition leader Anwar Ibrahim vowed on Tuesday to lead a "fierce movement" to reform the country's electoral system and challenge the results of an election he lost, starting with a rally of supporters this week. Anwar has refused to accept the victory of the long-ruling Barisan Nasional (BN) coalition in Sunday's election, saying that the result was tainted by widespread fraud, including the use of foreign immigrants to vote for the governing alliance.

Prime Minister Najib Razak's BN won 133 seats in the 222-member parliament, well short of the two-thirds majority it lost in 2008.

By Jeremy Wagstaff KUALA LUMPUR (Reuters) - Ahead of Malaysia's elections on Sunday, independent online media say they are being targeted in Internet attacks which filter content and throttle access to websites, threatening to deprive voters of their main source of independent reporting. Independent online news sites have emerged in recent years to challenge the dominance of mostly government-linked traditional media. The government denies any attempts to hobble access to the Internet in the run-up to a close-fought election.

Anwar Ibrahim vowed Tuesday his Malaysian opposition would soon present evidence of government cheating in bitterly fought weekend elections as he called for a "fierce" campaign for electoral reform. Anwar insisted his three-party Pakatan Rakyat (People's Pact) alliance would not back down from its insistence that victory was stolen from it last Sunday, setting the stage for an extended battle with the government for public opinion.
