Militants have attacked police guarding the largest Eid gathering in Bangladesh, throwing homemade bombs and launching a gun attack.
More than 250,000 people had gathered for Eid prayers at the Sholakia field in Kishoreganj district when the attack on a security checkpoint began.
Police say four people, including two officers and one attacker, were killed.
Last week, militants stormed the Holey Artisan Bakery cafe in Dhaka, killing at least 20, most of them foreigners.
That attack was claimed by so-called Islamic State, although the government said the attackers belonged to a local militant group.
Information Minister Hasanul Haq Inu described it as a “terrorist strike… against the normal practices of Islam”. The attackers were “out to create a destabilisation process to oust” the government, he added.
There have been security fears in Dhaka following last Friday’s attack on the cafe.
There were tight checks at some Eid services in the capital, with scanners and sniffer dogs used to check for bombs before worshippers could enter, AFP reported. Many people could be seen weeping during the services, while a local cleric issued a prayer to “protect our children from the evils of terrorism”, AFP added.
Bangladesh has also seen a spate of attacks on secular bloggers, gay activists, academics and members of religious minorities, with more than 40 killed since February 2013. Many of the attacks have been claimed by Islamic State militants or al-Qaeda affiliates, although the government has blamed local groups and the opposition instead. The opposition denies the claims.
