More than 200 Bengali-speaking Muslim migrants who were stranded on the border between India and Bangladesh have left the area, but it is not clear where they went.
Both countries deny accepting the men, women and children - mostly snake charmers.
Indian Border Security Force officials said today (Thursday) the group slipped into Bangladesh under cover of darkness, apparently with the help of the Bangladesh (Rifles, the) paramilitary force guarding that country's border.
In Dhaka, a Bangladesh border official denied that his country had accepted the group and suggested that Indian guards removed the migrants from the border area overnight.
The migrants had been trapped for nearly a week in a so-called "no man's land" between the two countries, as New Delhi and Dhaka argued about their nationality.
India says they are Bangladeshi nationals illegally trying to cross into India's West Bengal state. Dhaka insists the migrants are Bengali-speaking Indian Muslims.
Relations between India and Bangladesh have traditionally been good, but have soured recently after New Delhi last month announced a crackdown on illegal immigrants from Bangladesh. Indian officials say there are about 20-million Bangladeshis living illegally in the country, and that they pose a security risk.
Bangladesh denies any of its nationals are in India and accused Indian border troops of attempting to force hundreds of Bengali-speaking Muslims into Bangladesh during the past weeks. India denies the charge.
