Constitutional order could be re-established in Niger through diplomacy if Ecowas leaders engaged the military junta in "good faith", the Trades Union Congress (TUC) said.

"We hold a strong view that any attempt to remove the Tchiani-led military junta in Niger by force will further escalate the tension and the insecurity in the region,” TUC secretary general Yaw Baah said in a statement.

The West African regional bloc Ecowas has threatened military action against the military junta which overthrew President Mohamed Bazoum last month.

The junta has proposed a three-year transition to civilian rule, but Ecowas has rejected it.

The regional bloc has also imposed sanctions on Niger.

Traders in Ghana say they are now experiencing difficulties in importing vegetables such as onions from Niger, and prices have increased.

Ghana imports about 70% of its onions from Niger. In 2021, Niger exported about $23m (£18m) worth of onions to Ghana and other West African countries.
