DHAKA, March 24 (Xinhua) -- A suspected suicide bomber died after blowing himself up near Bangladesh's principal airport in capital Dhaka on Friday night, a police official said.
"A youth (aged about 25) blew himself up with a bomb inside his bag," a Dhaka Metropolitan Police official said, on condition of anonymity.
No others were injured in the blast.
No one has yet to claim responsibility for the attack.
A high alert was put on strategically important places including airports and prisons in Bangladesh last Friday, following a "suicide blast" at the proposed headquarters of the country's elite force Rapid Action Battalion (RAB) in capital Dhaka.
The suicide bomber died and two cops were injured in last Friday's blast, as the bomb the suspected militant was carrying exploded at the proposed headquarters of Bangladesh's elite force RAB near Hazrat Shahjalal International Airport in Dhaka.
Last Friday's incident took place a day after Bangladesh police stormed a militant hideout at Sitakunda on the outskirts of the country's seaport city Chittagong, some 242 km southeast of Dhaka.
Five including four militants of Neo-JMB, an offshoot of the banned militant outfit Jamaatul Mujahideen Bangladesh, were killed during the raid.
At least two of them reportedly blew themselves up in suicide explosions and two others were shot by the police.
Neo-JMB has been blamed for an attack on the Holey Artisan Bakery in Dhaka's diplomatic quarter last July, in which 20 hostages, mostly foreigners, were killed.
In the wake of the Dhaka cafe attack, Bangladesh police have conducted series of large-scale operations against militants.
