Will the death of Chad’s president create a security vacuum?

World leaders pay tribute to Idriss Deby, Chad’s president for more than 30 years, who has died at 68.

General Mahamat Idriss Deby, 37, will take over as president after death of his father, according to new charter.

President of more than 30 years had fought off several rebellions and was increasingly seen as silencing rivals.
