News of Chadian President Idriss Deby’s shock death met tributes and condolences as world powers mourned the passing of an ally seen as critical in the fight against security threats in the Sahel region.

In a statement on Tuesday Chad’s military said Deby died of wounds sustained during a visit to front lines in the country’s north where government troops are battling rebels in the restive border region with Libya.

Deby, who governed the central African country since rising to power in a 1990 coup, had a day earlier secured a sixth consecutive term in office.

His 37-year-old son, four-star General Mahamat Idriss Deby, has been named as the interim leader of an 18-month military transitional council.

Here’s how the world reacted to the news of Deby’s death:

African Union

The head of the African Union Moussa Faki Mahamat, a former Chadian prime minister, said he was saddened by Deby’s death, sending his condolences to his family.

“It is with great dismay and deep emotion that I learned of the death today of President Idriss Deby Itno,” said Faki, who was Chad’s prime minister from 2003 to 2005.

He called Deby a “great statesman and recognised military leader. I extend my sincere condolences to the Chadian people and his family”.

France

France deplored Deby’s passing and said it took note of the creation of an interim military body, urging a quick return to civilian rule and a peaceful transition.

“France lost a brave friend,” President Emmanuel Macron’s office said in a statement. “It expresses its strong attachment to Chad’s stability and territorial integrity.”

After a new transitional military council led by one of Deby’s sons pledged to hold elections in 18 months, French Foreign Minister Le Drian warned that the delay should be “limited”.

United States

The White House offered its “sincere condolences” to the people of Chad on the death of Deby.

“We condemn recent violence and loss of life in Chad,” a White House spokesperson said in a statement.

“We support a peaceful transition of power in accordance with the Chadian constitution.”

European Union

The European Union’s foreign affairs chief, Josep Borrell, expressed his condolences to the family, and to the Chadian authorities and people.

“The EU calls on all relevant actors to act responsibly, the immediate priority being the stability of the country and the region,” Borrell said.

Meanwhile, European Council President Charles Michel said that “the stability, the security and the [territorial] integrity of the country have to be preserved.”

United Nations

Volkan Bozkir, president of the UN general assembly, tweeted his “most sincere condolences”.
