Chad has closed its border with neighbouring Sudan following deadly clashes linked to the ongoing conflict in Sudan that killed five Chadian soldiers.

The Chadian government announced the closure on Monday, citing repeated incursions and security violations by armed groups involved in Sudan’s war.

Officials said the latest violence erupted in the border town of Tine, where fighting broke out between Sudan’s paramilitary Rapid Support Forces and troops loyal to the government.

In addition to the five soldiers killed, three civilians died and at least 12 others were injured during the clashes. Authorities also reported damage to property in the affected communities.

The incident highlights the growing spillover of Sudan’s civil war into neighbouring countries, with Chad facing repeated security and humanitarian pressures along its eastern border.

The conflict, which is approaching its fourth year, has triggered one of the world’s worst humanitarian crises. The United Nations says the war has displaced millions and fueled severe food shortages across the region.

Chadian officials said security forces have been reinforced along the border to prevent further incursions and protect civilians.
