The body of Awami League Presidium member Sheikh Fazlul Karim Selim’s grandson Zayan Chowdhury, who was killed in the bomb attacks in Sri Lanka on Sunday, is set to arrive in Bangladesh around 11am on Tuesday, said the ruling MP's personal aide Imrul Haque.

Nearly 300 people were killed and at least 450 injured in bomb blasts that ripped through churches and luxury hotels in Colombo on Easter Sunday, the first major attack on the Indian Ocean island since the end of a civil war a decade ago.

Zayan, one of the two sons of Sheikh Selim’s daughter Sheikh Amena Sultana Sonia, died in an explosion in the hotel where the family was staying.

Zayan’s father Mashiul Haque Chowdhury Prince was also injured in the blast and later admitted to a local hospital, according to Imrul.

The eight-year-old was having breakfast with his father at a restaurant on the ground floor of the hotel in Colombo that came under attack along with several other hotels and churches during Easter Sunday celebrations.

Zayan’s younger brother Zohan Chowdhary and mother Sheikh Amina Sultana Sonia were in their hotel room during the blast. The family went to Sri Lanka on a vacation.
