Niger Soldiers have gone on national TV in Niger to announce they have carried out a coup.
Niger Soldiers said they had dissolved the constitution, suspended all institutions and closed the West African country’s borders, BBC reports.
Niger President Mohamed Bazoum has been held by troops from the presidential guard since early on Wednesday.
US Secretary of State Antony Blinken conveyed Washington’s “unwavering support” in a call to Mr Bazoum.
UN Secretary-General Antonio Guterres also said he had spoken to the president and offered the UN’s full support for him.
Mr Bazoum is a key Western ally in the fight against Islamist militancy in West Africa.
In the TV announcement on Wednesday Col Maj Amadou Abdramane, with nine other uniformed Niger soldiers behind him, said: “We, the defence and security forces have decided to put an end to the regime you know.
“This follows the continuing deterioration of the security situation and poor economic and social governance.”
He also said that all of the country’s institutions had been suspended and that the heads of the ministries would take care of day-to-day business.
“All external partners are asked not to interfere,” he went on.
“Land and air borders are closed until the situation has stabilised.” He added a night curfew would take effect from 22:00 until 05:00 local time until further notice.
He said the soldiers were acting for the National Council for the Safeguard of the Homeland (CLSP).
