DHAKA, Bangladesh - The government put thousands of security forces on the streets of Dhaka and nearby Tongi Sunday as a strike to protest the killing of an opposition lawmaker brought Bangladesh to a standstill.

Ahsanullah Master, a member of the main opposition Awami League, was gunned down at a party rally Friday in Tongi. There have been no arrests and his killing has set off widespread unrest in the two cities.

Authorities said they suspect his killing may be connected to a feud within his party. But Awami League blamed government supporters and called a one-day strike.

In Dkaha, a city of 10 million, shops and schools were closed and streets were mostly empty Sunday, a work day in mostly Muslim Bangladesh.

Riot police manned barbed-wire barricades erected around the Awami League headquarters in central Dhaka, preventing its members from taking to the streets.

Security was similarly tight in Tongi and more than 60 other cities and towns where the strike took hold, the opposition said.

Authorities deployed several thousand police and paramilitary soldiers on the streets of Dhaka and Tongi to prevent violence, Dhaka police chief Ashraful Huda said.

On Friday and Saturday, riot police clashed with thousands of opposition supporters who rampaged through Dhaka and Tongi to protest Master's shooting.

Angry mobs attacked government buildings, shops, trains, cars and buses. One person was killed when police fired shots to disperse a mob in Tongi on Friday.

Police have arrested nearly 150 opposition protesters for rioting, a police official said on condition of anonymity.
