TEHRAN, Iran (AP) -- An Iranian group that claims its members are dedicated to becoming suicide bombers warned the United States and Britain on Saturday that they will strike coalition military bases in Iraq if Tehran's nuclear facilities are attacked.

Mohammad Ali Samadi, spokesman for Esteshadion, or Martyrdom Seekers, boasted of having hundreds of potential bombers in his talk at a seminar on suicide-bombings tactics at Tehran's Khajeh Nasir University.

"With more than 1,000 trained martyrdom-seekers, we are ready to attack the American and British sensitive points if they attack Iran's nuclear facilities," Samadi said.

"If they strike, we have a lot of volunteers. Their (U.S. and British) sensitive places are quiet close to Iranian borders," Samadi said.
