DHAKA (AFP) - Dozens were injured in violent clashes between protesters and police in major cities across Bangladesh Sunday as a nationwide strike called by the main opposition party brought the country to a standstill. The clashes erupted as Bangladesh Nationalist Party activists staged day-long protests over the eviction of BNP leader and former two-time premier Khaleda Zia from her home on Saturday, triggering late-night rioting. Officers fired rubber bullets and used batons against strike supporters in front of the party headquarters in Dhaka and its regional office in the second biggest city of Chittagong, police said. A former commerce minister was among a dozen injured in Chittagong, the countrys main port city, while a police inspector was hit by a small bomb in northern Mymensingh city, local police told AFP. A police van was burnt out by a petrol bomb in Dhaka, where security was tight with at least 10,000 heavily armed policemen and 2,000 members of an elite Rapid Action Battalion out in force, police spokesman Walid Hossain said. Hossain said police swung into action at several sites in the capital, using rubber bullets, tear gas and batons after opposition activists became violent. Barring these isolated incidents, the strike was largely peaceful, he said. At least 100 opposition activists have been arrested on charges of attacking police with small bombs and bricks and damaging vehicles in cities and towns across the country, police officers told AFP. Security forces barricaded the BNP headquarters in central Dhaka with barbed wire and used coloured water to douse lawyers supporting the strike outside the countrys supreme court. Shops, businesses and schools were closed in all the major cities and towns across the country, and police said road transport in Dhaka and major cities had almost ground to a halt. Bus and lorry services have also been cut, snapping links between the capital and other cities and towns and stranding millions of people who planned to visit village homes to celebrate Eidul Azha. On Saturday Dhaka erupted into violence after news spread that Zia has been evicted from the Dhaka home where she has been living for 38 years. Police fired rubber bullets and tear gas to disperse the BNP supporters who went on the rampage torching and damaging dozens of vehicles. At least 21 people were detained. Officials said Zia willingly left the sprawling house - leased to her by the government after her husband, president Ziaur Rahman, was murdered in 1981 - as a court deadline to vacate the home expired Friday. Zia told reporters on Saturday police officers had entered her bedroom, dragged her out and pushed her into a car. She said she was removed illegally as the countrys highest court was still hearing an appeal against a lower courts eviction order. In another incident, two people were killed in a suicide bombing at a ruling party lawmakers house in western Bangladesh on Saturday. Police would not say whether the blast linked to Zias eviction. The lawmaker was unhurt. In a statement on Saturday night, the US Embassy said it was closely monitoring events related to Zias residence in the cantonment. We hope that these issues can be resolved through dialogue and established legal procedures. We call on all sides to exercise restraint, the statement signed by embassy spokesman Patricia Hill said.
