The Economic Community of West African States, ECOWAS, "strongly condemns the violence and all attempts to disrupt the constitutional order and rule of law in Guinea-Bissau," read a statement released by the regional bloc.
"ECOWAS further calls for the arrest and prosecution of the perpetrators of the incident in accordance with the law," the statement added.
The statement by ECOWAS was in reaction to clashes in Guinea-Bissau that broke out in the capital, Bissau, on Thursday between members of the national guard and special forces of the presidential guard. Two people died as a result.
Calm returned to the small nation with a history of instability by mid-morning Friday following the announcement that the army had captured Colonel Victor Tchongo, commander of the national guard.
Members of the national guard Thursday evening stormed a police station to extract Finance Minister Souleiman Seidi and Secretary of the Treasury Antonio Monteiro, according to army and intelligence officers.
The two government members were being questioned about the withdrawal of $10 million from state accounts. They had been detained under orders of state prosecutors, who are named by the president.
The national guard, on the other hand, is under the control of the Interior Ministry, which like most ministries in the country, is dominated by the PAIGC party, whose coalition won the June 2023 elections.
The two government members were detained again after the army removed them from National Guard control.
