The government also asked Indians not to travel Niger in the upcoming days.

The government also asked them to reconsider their travel plans until the situation normalizes.

How to contact Indian Embassy:

Indian nationals can reach emergency contact in the Embassy of India, Niamey (+ 227 9975 9975) for any assistance.

Situation in Niger:

UN Secretary-General António Guterres has voiced concern about the reported “deplorable living conditions” of the President of Niger in arbitrary detention, his spokesperson said in a note to journalists published on Wednesday evening.

President Mohamed Bazoum and his family are believed to be living without electricity, water, food or medicine, according to media reports.

The democratically elected leader has been detained since soldiers seized power on 26 July.

"The Secretary-General reiterates his concern for the health and safety of the President and his family and once again calls for his immediate and unconditional release and reinstatement as head of state," the note said.

Guterres was also alarmed over continuing reports about the arrest of several members of the Government and urgently called for their unconditional release.

The UN fears the crisis in Niger could impact the wider West African region and continues to underscore the need to ensure ongoing humanitarian support to some 4.3 million people in the country.

This week, the World Food Programme (WFP) assisted more than 12,000 people in the Maradi region in south-central Niger, UN deputy spokesperson Farhan Haq said on Thursday.
