Indian police have released sketches of three people believed to be responsible for a series of deadly bomb attacks that killed 13 people in northern India Friday.
The explosions, which police say targeted lawyers, occurred at the courthouses of three northern cities -- Lucknow, Varanasi and Faizabad.
More than 60 others were wounded in the blasts.
Federal officials blame the attack on militants trying to spark unrest between India's Hindu and Muslim populations. However, officials in the northern state of Uttar Pradesh say they believe the attacks there were aimed at lawyers who have refused to defend terrorism suspects.
Last week, police in the capital of Uttar Pradesh, Lucknow, arrested three alleged terrorists for planning an attack on a politician. Lawyers in the city refused to defend the suspects, who also alleged that they were assaulted as they were led to court.
