Man in bomb probe shot dead following attack on FBI agent

A Chechen immigrant was shot to death by authorities while being questioned in the Boston Marathon bombing case yesterday after he lunged at an FBI agent with a knife, officials said.

Ibragim Todashev, a 27-year-old mixed martial arts fighter, was gunned down at his home during a meeting with the agent and two Massachusetts state troopers, authorities said.

The agent was taken to a hospital with injuries that were not life-threatening.
