The six killed Saturday died after a series of explosions took place on a road near an Islamic religious school and close to the building under siege. At least 25 people were wounded in the attacks and 78 civilians rescued from the building after troops broke a section of the compound wall where the building is located the army spokesman said. The gunbattle with suspected militants came after a man killed himself on Friday by detonating explosives near a police post on a busy road near the airport in Dhaka, Bangladesh's capital.
