Security has been increased at Buddhist temples and tourist attractions in Northern India, after an attack at the holiest Buddhist shrine where the Buddha himself is said to have gained enlightenment.

Two monks were injured in a series small bomb blasts at the Bodh Gaya Temple Complex in Bihar state.  Witnesses said some of the bombs exploded close to the Bodhi tree, believed to be a descendant of the very tree that the Buddha sat under during the Fifth or Sixth Century BCE, when he achieved enlightenment.

There’s been no claim of responsibility but the Indian government acknowledges it was a terror attack. Prime Minister Manmohan Singh said, “Such attacks on religious places will be never be tolerated.”

Local reports say the Indian government had been planning tighter security at Buddhist sites because of rising tensions related to the ethnic conflict in neighboring Myanmar between Buddhists and Muslims.
