The Rajasthan government is moving to expel illegal Bangladeshi migrant workers after a series of bomb blasts, a high-ranking official said.While government officials haven't named any suspects in Tuesday's blasts in Jaipur, media reports have quoted police as saying they are investigating possible links between the attacks and the Bangladesh-based Islamic extremist group Harkat-ul-Jehad-i-Islami.A previously unknown Islamic militant group calling itself the Indian Mujahedeen claimed responsibility Thursday, saying it planted bicycles packed with explosives on the city's crowded streets.Parliamentary Affairs Minister, Rajendra Singh Rathore, said late Friday the government would investigate how many illegal migrant workers from Bangladesh are in the state and expel them.Thousands of Bangladeshis, most of them Muslims, illegally enter India every year looking for jobs, a charge Bangladesh denies.Some experts estimate as many as 20 million Bangladeshis are in India illegally, working as unskilled construction laborers or domestic helpers.
