Niger’s military leaders have warned against any armed intervention in the country as West African heads of state gather in Nigeria’s capital for an emergency summit to decide on further actions to pressure the army to restore constitutional order.

Heads of state of the 15-member Economic Community of West African States (ECOWAS) and the eight-member West African Economic and Monetary Union could suspend Niger from its institutions, cut off the country from the regional central bank and financial market, and close borders.

Niger’s eastern neighbour Chad, a non-member of both regional organisations, has been invited to the ECOWAS summit, a statement from the Chadian president’s office said on Saturday.

Niger is one of the poorest countries in the world, receiving close to $US2 billion ($3 billion) a year in official development assistance, according to the World Bank.

It is also a security partner of former colonial power France and the United States, which both use it as a base to fight an Islamist insurgency in West and Central Africa’s wider Sahel region.

The military coup in Niger has been widely condemned by its neighbours and international partners including the United States, the United Nations, the African Union, the European Union and former colonial power France who have all refused to recognise the new leaders and demanded Bazoum be restored to power.

The West African leaders could for the first time consider a military intervention to restore President Mohamed Bazoum who was ousted when General Abdourahamane Tiani was declared the new head of state on Friday.

Ahead of the Sunday summit, the military leaders in Niger warned against any military intervention in a statement read on Niger national television on Saturday night.

“The objective of the (ECOWAS) meeting is to approve a plan of aggression against Niger through an imminent military intervention in Niamey in collaboration with other African countries that are non-members of ECOWAS, and certain Western countries,” junta spokesman Colonel Amadou Abdramane said.

“We want to once more remind ECOWAS or any other adventurer, of our firm determination to defend our homeland.”

Invited by the military leaders, pro-junta supporters took to the streets of the capital early on Sunday to show their support and reject any intervention by ECOWAS.

The protesters gathered in a public square in central Niamey, with some heading to the French Embassy chanting anti-French slogans and holding placards reading: “Down with France!” “France Out!”, according to a Reuters reporter.

Some youths threw stones at the embassy building before the protesters were dispersed by Niger national guard.

The military rulers later issued a call on Niger national TV asking protesters to abstain from vandalism and destruction of public or private property.

Bazoum has not been heard from since early Thursday when he was confined within the presidential palace, although the European Union, France and others say they still recognise him as the legitimate president.

The EU and France have cut off financial support to Niger and the United States has threatened to do the same.

After an emergency meeting on Friday, the African Union issued a statement demanding the military return to their barracks and restore constitutional order within 15 days.

It did not say what would happen after that.
