More than 100,000 students have linked their hands to form human chains in Bangladesh to protest two attacks last month by suspected Islamist militants.

The students from hundreds of colleges and universities in Dhaka and other cities took part in the protest Monday as part of a campaign to create awareness about the rise of Islamic extremism in the country.

The protest came after suspected Islamist militants killed 20 people, including 17 foreigners, in an attack on a popular restaurant in Dhaka a month ago. That was followed by an attack on an Eid congregation in central Bangladesh that left three people dead.

The Islamic State group has claimed responsibility for the attacks, but Bangladesh authorities have blamed the banned group Jumatul Mujahedeen Bangladesh.
