Kathmandu, Sep 15 - Indian Foreign Secretary Nirupama Rao's Nepal visit will be followed by a meeting between the home secretaries of the two countries to discuss the 'entire gamut of bilateral security issues', underlining New Delhi's growing security concerns in Nepal, especially after the terror attacks in Mumbai last year that killed over 170 people.

Rao, who concluded her two-day visit Tuesday meeting Nepal's embattled Prime Minister Madhav Kumar Nepal, has reiterated India's security concerns and the use of Nepali territory for anti-India activities.

The renewed concern comes after Indian police made several arrests related to terror attacks and smuggling of fake currency in which the arrested people were found to have links to Nepal.

At a press conference before her departure Tuesday, Rao said the alliance government of Nepal has given an unequivocal commitment that anti-India activities will not be allowed on Nepali soil.

According to Nepal's foreign ministry spokesman Madan Kumar Bhattarai, Rao had broached the issue of signing a revised extradition treaty, which would allow the deportation of third country nationals.

The treaty was scheduled to be signed several years ago but was shelved due to pressure from the Maoists.

India and Nepal have also been discussing for several years a treaty on mutual legal assistance that will, among other things, allow the police of one country to sit during the interrogation of a criminal by the force of the neighbouring country.
