A heavy exchange of fire between Indian and Bangladeshi border guards lasting seven hours has killed a schoolboy and injured some soldiers, officials say.
The incident happened at a border point in the Dinajpur district.
A spokesman for India's Border Security Force said the fighting began when an Indian border guard was kidnapped by a gang of smugglers from Bangladesh.
The Bangladeshi border force, the Bangladesh Rifles, says it was sparked by unprovoked firing from India.
They say the Indian soldier was caught by Bangladeshi villagers on their side of the border and formally handed over after senior officers from the two sides met to diffuse tensions.
The two countries share a long and porous border which is not properly demarcated.
Over the past decade they have regularly exchanged shelling and small arms fire over the frontier.
Correspondents say that such incidents have not seriously interfered with generally friendly relations between Delhi and Dhaka.
However, tensions increased in 2006 when India began fencing off the 4,000km (2,500 mile) border to keep out what it described as illegal immigrants and "cross-border insurgents".
