Niger junta announces new government with 21 ministers

Niger's junta named 21 ministers to a new government on state television overnight, forcing its agenda before a summit on Thursday of regional leaders who have demanded that they end their military takeover in the west African nation.

West African heads of state hold a summit in Nigeria aiming to agree on a plan of action for Niger, where coup leaders have refused to stand down despite the bloc's threat that it could use force to restore democracy.

Since the July 26 power grab shocked the region, the defiant junta has rebuffed diplomatic overtures and ignored an August 6 deadline from the Economic Community of West African States (ECOWAS) to reinstate ousted president Mohamed Bazoum.

Mahamane Roufai Laouali, cited as "Secretary General of the Government", read out the names on television without specifying any further plans. The government is half the size of the previous one.

UN Secretary-General Antonio Guterres voiced concern about Bazoum and his family after his party reported that they were being detained at the presidential residence without electricity or running water, and had gone days without fresh food.

"The Secretary-General... once again calls for his immediate, unconditional release and his reinstatement as Head of State," a UN spokesperson said on Wednesday.

The meeting in the Nigerian capital, Abuja, could prove a pivotal moment in the standoff. The bloc's leaders are expected to agree on next steps, which could include military intervention - something an ECOWAS official has said would be a last resort.

Envoys of the Nigerian president, and ECOWAS chair, Bola Tinubu met coup leaders in the capital, Niamey, on Wednesday, offering a glimmer of hope for dialogue after previous missions were spurned.

Any escalation would further destabilise West Africa's Sahel region, where a long-running insurgency has displaced millions and stoked a hunger crisis.

The coup was triggered by internal politics but it has evolved into an international entanglement, with ECOWAS, the United Nations and Western countries putting pressure on the junta to stand down, while military governments in neighbouring Mali and Burkina Faso have vowed to defend it.
