American blogger hacked to death in Bangladesh

A U.S. blogger who wrote against religious fundamentalism was hacked to death in Bangladesh's capital.

Avijit Roy and his wife, Rafida Ahmed, were attacked late Thursday after leaving a book fair at Dhaka University, police said.  Ahmed was seriously wounded in the attack.

The Bangladesh Daily Star reported there were witnesses to the attack, but no one came forward to help the couple or apprehend the assailants.

There has been no immediate claim of responsibility for the attack.

Roy's brother said his older brother, who was born in Bangladesh, had returned to the country earlier this month and was set to travel back to the U.S. next month.

There have been similar attacks on writers in Bangladesh, which is a Muslim-majority nation. 

There has been no claim of responsibility, but religious fanatics are believed to be responsible for the attacks, investigators said.
