ADDIS ABABA, Jan. 8 (Xinhua) -- Chairperson of African Union (AU) Commission Moussa Faki Mahamat on Monday condemned a failed coup attempt in Gabon.

"The African Union strongly condemns the coup attempt this morning in Gabon," Faki Mahamat said in a statement via twitter.

He also stressed that the 55-member pan African bloc's firm stance against unconstitutional moves, saying that "I reaffirm the AU's total rejection of all unconstitutional change of power."

Gabon, soon after the failed attempt, revealed the arrest of four soldiers who are said to have attempted to take control of the national radio station on Monday morning.

Soldiers entered the national radio station in Libreville around 4 a.m. local time to read a statement in which they announced the setting up of a "national council of the restoration."

In the statement, Ondo Obiang Kelly, lieutenant of the Republican Guard, announced that they were disappointed by the message delivered on December 31 by President Ali Bongo, which "rather heightened doubts about his ability to assume the office of President of the Republic."

The lieutenant later managed to flee but four other soldiers were arrested by the military following an intervention. The situation is under control and order will be completely restored in two or three hours, said the government spokesman.

President Ali Bongo is currently recovering in Morocco, after suffering a stroke in late October 2018. In the message he gave to the nation on December 31, he expressed that the condition of his health is improving.
