Daily US Times: Idriss Déby, the president of Chad, has died suddenly in clashes with rebels in the north of the country at the weekend, the army has said on state TV.
Provisional results published on Monday from the election on 11 April projected he would win a sixth term in office, with 80% of the vote.
The parliament and government have been dissolved. A military council will govern for the next 18 months.
The 68-year-old Mr Déby was one of Africa’s longest-serving leaders.
Mr Déby first came to power in an armed uprising in 1990.
An army general said in a statement read out on state TV that Mr Déby “breathed his last defending the sovereign nation on the battlefield”,
At the weekend, he had gone to the front line to visit troops battling rebels based across the border in Libya.
The military council will be led by Mahamat Idriss Déby Itno, 37, a four-star general and the son of the late president.
The rebels, from a group calling itself Fact (the Front for Change and Concord in Chad), attacked a border post on election day.
They were advancing on the country’s capital, N’Djamena, several hundred kilometres to the south.
On Saturday, the clashes with the army began. An army general told Reuters that 300 insurgents were killed and 150 captured.
Thirty six government soldiers were killed and 5 killed, he said. The figures could not immediately be verified.
