The vicious war in Sudan between the army and a powerful paramilitary group has reached the grim milestone of 100 days with no signs of respite.
On April 15, a power struggle between army chief Abdel Fattah al-Burhan and his former deputy, Rapid Support Forces (RSF) commander Mohamed Hamdan “Hemedti” Dagalo, burst into an all-out conflict, killing thousands of people, forcing millions from their homes and exacerbating an acute humanitarian crisis.
Here are the key developments in the war so far.
April 15: Fighting erupts
On April 15, heavy gunfire and explosions rock the capital, Khartoum, sparking panic in the city and beyond.
The army and the RSF each accuse the other of attacking first.
The clashes come after years of instability and repeated coups.
Fighting also erupts in the western region of Darfur, which is still reeling from a brutal war that started in 2003 under longtime ruler Omar al-Bashir.
April 22: Evacuations begin
Several countries rush to evacuate their nationals by air or land.
Thousands flee in the exodus while many embassies are ransacked.
Millions of Sudanese remain trapped in their homes with supplies of water, food, medicines and other basic items running low.
April 25: Failed truce
The United States and Saudi Arabia negotiate a 72-hour truce but it is quickly violated. A series of further truce deals that follow falter.
Ahmed Harun, a leading figure in the government of al-Bashir, who was removed by the army in the wake of months-long popular protests, says he has escaped from prison.
The army says that al-Bashir, who is wanted by the International Criminal Court (ICC) on genocide charges over the war in Darfur, was transferred to a hospital before the fighting began.

Aid agencies raise alarm as humanitarian efforts are interrupted across the country. Organisations struggle to resume operations while ensuring the safety of their workers.

The Sudanese army and the RSF agree to extend the faltering ceasefire for “an additional 72 hours” amid continuing violence in Khartoum and the western Darfur region.
But fighting continues as warplanes patrol over the capital’s northern suburbs and fighters on the ground exchange artillery and heavy machine-gun fire, according to witnesses.

June 3: Army brings reinforcements
The Sudanese army calls in reinforcements, sparking fear among Khartoum residents that the conflict will worsen.
The army tries to take control of a military base in the capital that belongs to the RSF.

June 7: Fuel fire erupts
A major blaze engulfs a fuel facility in Khartoum as fighting rages for a crucial weapons depot. Smoke billows from the fuel-storage site that is close to an army base and the weapons manufacturing company.
June 8: Orphans evacuated
At least 280 children and 70 of their carers are taken from the Al-Mayqoma orphanage in Khartoum to a new facility in Madani, about 135km (85 miles) southeast of the capital. That the transfer takes finally place eight weeks into the conflict highlights the difficulty in obtaining security guarantees from warring parties.
