Chad has announced the closure of its eastern border with Sudan "until further notice" in response to repeated incursions by Sudanese armed groups and escalating conflict near its territory.

• The closure follows heavy fighting in the border town of al-Tina, which resulted in the deaths of five soldiers and three civilians.
• Key organizations involved are Sudan's Rapid Support Forces (RSF) and local fighters aligned with the Sudanese army.
• This measure aims to prevent the conflict from spreading into Chad and safeguard its citizens and refugee communities, though humanitarian exemptions may be granted.
