A mob in a village from India's north-eastern state of Tripura has attacked a village in Bangladesh, setting fire to several houses.
The attack comes after the villagers said a local farmer, Nirmal Pal, had been kidnapped and taken into Bangladesh by the guerrillas of the National Liberation Front of Tripura (NLFT).
More than 10 people, including three government officials, have been kidnapped by the rebels in Tripura in the past two days.
Tripura police officials said that some robbers from Bangladesh had assisted the NLFT militants when they abducted Nirmal Pal on Monday.
They said tempers rose in the village of South Baruakandi and a mob gathered with swords, spears, bows and arrows.
In the early hours of Tuesday morning, the mob crossed the border and stormed into Chungibari village , several kilometres inside Bangladesh.
They set fire to several houses.
It is not yet clear whether any Bangladeshis were killed or injured in the attack.
The Indian villagers returned home at dawn.
As news of the attack spread, villagers on the Bangladesh side gathered near the
border with weapons.
Indian and Bangladeshi border security forces were rushed to the area to prevent any further attacks but tension was said to be running high.
Bangladesh usually denies that Indian militants are on its territory
Meanwhile, Indian intelligence officials say Bangladesh police have arrested nine NLFT rebels from the country's eastern town of Saidabad .
The rebels were reported to be travelling on a bus between the towns of Burichong and Brahmanbaria when they were stopped at a bridge on Saturday.
arrested included two senior NLFT leaders, Mangal Debbarma and Sumanta Debbarma.
Last December Bangladesh, which normally denies the presence of Indian militants in its territory, admitted that two NLFT factions had fought a gun battle in Burichong, in
which seven rebels died.
One Bangladeshi woman in whose house rebels of one NLFT faction were
staying, was also killed in the fighting.
