The recovery of a sophisticated sniper rifle and military suits in Chittagong yesterday and Friday's suicide blast at an Ahmadiyya mosque in Rajshahi are alarming additions to the country's security situation, says a security analyst.

A suicide bomber kills 21 worshipers during Friday prayers in a packed Shia mosque in eastern Saudi Arabia in an attack claimed by the Islamic State militant group.

A suicide bomb blast in Afghanistan's eastern city of Jalalabad kills 33 people and injures more than 100 outside a bank where government workers collect salaries.
