The United States has warned that terrorist groups could take advantage of the political instability and weak security situation in Nepal, dpa reported
"Given Nepal's continued instability, there is a possibility that members of extremist groups could transit Nepal, especially into India," said the latest Country Reports on Terrorism, released by the US Department of State Thursday.
The report said there were, however, no indications that Nepal was currently a safe haven or financial centre for international terrorists.
"The large ungoverned space along the Nepal/Indian border exacerbates this vulnerability, as do security shortfalls at Tribhuvan Airport, Nepal's international airport," the report said.
"In June, Lashkar-e-Taiba member Muhammad Omar Madni travelled through Nepal en route to New Delhi," it said.
Nepal shares an 1,800-kilometre open border with India, delineated only by marker posts and rivers.
Questions on Nepal's airport security first arose after Taliban militants hijacked an Indian Airlines flight from Kathmandu to Delhi in December 1999.
The plane was taken via several locations to Kandahar, Afghanistan. The hijackers fatally stabbed one passenger, and released the others in exchange for three Taliban militants detained in an Indian prison.
