Nepal has asked all citizens travelling to India to carry documents that could verify their identities.

In a press release Monday, the Nepali foreign ministry urged its citizens planning to travel to India to carry documents like passports, citizenship certificates or driving licenses.

"After recent incidents in India, the Indian administration has tightened the internal security," read the statement, referring to the Mumbai attacks.

"We have got information that a person is compulsorily asked to present identity card with photograph in hotel, while travelling and going for treatment and getting admitted to hospital," it said and urged Nepalis to carry government-issued documents for identity verification in India.

Nepalis and Indians are allowed to enter both the countries without any document and citizens of both countries travel freely across the two countries' open-border.
