NEW DELHI —  A series of synchronized small bombs shook India's high-tech hub Friday, killing one person and wounding at least six others, police said.

One woman was killed in an explosion at a bus stand in the city's Madiwala neighborhood, local police officer Ahmed Hussain told The Associated Press by telephone.

He said there had been three other explosions, though he had no immediate information on other casualties or the cause of the blasts.

Indian media reports said there had been up to six blasts and up to three people killed. Television footage showed police officers from bomb squads scouring the areas, covered with shattered glass. From the pictures, it appeared the blasts were relatively small.

Several Indian cities have been hit by serial blasts in recent months, attacks that have been blamed on Islamic militants.
