Police in Bangladesh have detained at least 200 people ahead of street marches planned by opposition parties this week.

Officials said Monday the arrests were made as supporters of a 14-party opposition alliance prepared to march to the capital, Dhaka, Tuesday to demand election reform.

Led by the Awami League, the alliance is pushing the government to implement reforms and remove members of the election commission before polls are held in January.

The group accuses election officials of favoring Prime Minister Khaleda Zia's government. It also is demanding a say in the caretaker government that will take office in October to oversee the election.

This week's march is the latest in a series of strikes and protests organized by the opposition to put pressure on Bangladesh's government.
