Dr. Manmohan Singh, Prime Minister of India, on Tuesday condemned the deadly attack at the Boston Marathon that left three people dead, including an eight-year-old boy, and injured more than hundred people.

"I am deeply shocked and saddened by the outrageous terrorist attack in Boston yesterday. This senseless and cowardly act of violence has struck a city that has long stood as the symbol of openness, learning, innovation and enterprise," said the PM in a message to United States President Barack Obama.

"The people of India join me in condemning the attack in the strongest terms. We stand in solidarity and sympathy with the bereaved families, the injured and the people of the United States."

Three people, including an eight-year-old boy, were killed by the blasts and over 150 people were injured. Some of them were said to be critically injured.

The first blast, which blew out the window of a store near the end of the race course at around 2:50 p.m.(1850 GMT), stunned the throng of people who had gathered in Copley Square for the race's finale. A few seconds later, a second blast sent waves of fear and horror through the crowd, according to Reuters.
