Three critically injured people died overnight in hospitals, raising the death toll to 10 in three explosive attacks that hit India's restive northeastern state of Assam, police said Tuesday. Another 59 people were injured in coordinated attacks on Monday, a day before an election campaign visit to the state by India's Prime Minister Manmohan Singh, said Bhaskar Mahanta, an inspector-general of state police. A spokeswoman for Singh's office, Deepak Sandhu, said the prime minister's trip, due later Tuesday, had not been canceled. G.M. Srivastava, the state's top police officer, blamed separatist United Liberation Front of Asom for Monday's explosions on the eve of the 30th anniversary of its founding, according to a report of Associated Press.
