Reuters – A blogger was hacked to death by machete-wielding assailants in the Bangladesh capital Dhaka on Monday, the second attack in five weeks on a critic of religious extremism in the Muslim-majority South Asian nation.

Washikur Rahman, a secular blogger, was attacked by young religious students on a busy street in the center of Dhaka on Monday morning, a police official said.

"Police on duty near the spot caught two attackers red-handed with three machetes as they were fleeing the scene after the incident," police official Humayan Kabir told Reuters.

The killing comes just weeks after U.S. secular blogger Avijit Roy was hacked to death while returning with his wife from a book fair in Dhaka. His wife, Rafida Bonya Ahmed, suffered head injuries and lost a finger in the February 26 attack.

The attacks come amidst a period of political turmoil in the country, with the government and main opposition group locked in a months-long standoff that has created a sense of deepening insecurity across the country.

In recent years, a string of secular-minded writers have been targeted by religious militants in Bangladesh as the government has tried to crackdown on hardline Islamist groups seeking to create a Sharia-based state in the nation.

Blogger Ahmed Rajib Haider was killed in 2013 near his home in Dhaka after he led a protest demanding capital punishment for Islamist leaders convicted of war crimes during Bangladesh's war for independence.

In 2004, Humayun Azad, a secular writer and professor at Dhaka University, was also attacked by militants while returning home from a Dhaka book fair. He later died in Germany while undergoing treatment.

Roy's wife, Ahmed, blamed her husband's murder in February on religious fanatics, and accused police on duty of not doing enough to stop the attack.

Roy's father also told reporters last week that "apparently no progress" had been made in resolving the case.

Mohammad Habibur Rahman, secretary of the Bangladesh Police Association and Superintendent of Police of Dhaka, said the police had been unfairly criticized over their handling of the crime.

"There are plenty of examples where our police force come forward to save people, risking their own lives," he said.

Media group Reporters Without Borders rated Bangladesh 146th among 180 countries in a ranking of press freedom last year.
