After three years of relentless conflict, the Sudanese war has now spilled across Chad’s borders. Border strikes, military tensions, and community unrest are forcing N’Djamena to confront a crisis it can no longer ignore.

Border conflict rages between Sudan and Chad

Since April 2023, Sudan has been torn apart by a brutal war between General Abdel Fattah al-Burhan’s army and the Rapid Support Forces (RSF) led by Mohamed Hamdan Dagolo, known as Hemedti. While Chad has publicly claimed neutrality, its actions tell a different story. N’Djamena has quietly backed the RSF, a decision that has sparked fierce debate. This alliance puts Chad in a precarious position: supporting a faction that has targeted the Zaghawa people in Darfur—yet the Zaghawa are a pillar of Chad’s own government. Weapons, reportedly funded by the United Arab Emirates, have been smuggled through key border towns like Amdjarass and Adré, a risky gamble with consequences that have now come to pass.

Tiné: a flammable cross-border town

Tiné exists on both sides of the Chad-Sudan border, with twin towns separated only by a thin line. These communities are home to the same Zaghawa people and serve as a critical escape route for civilians fleeing the horrors of Darfur’s violence. On February 21, 2026, the RSF seized control of the Sudanese side of Tiné, sparking immediate clashes with the Toroboro fighters—Chadian and Sudanese militias allied with General al-Burhan—as well as unapproved Chadian military units. The city was retaken within days. In response to the escalating insecurity, Chad announced the closure of its border. Yet fighting persisted, confirming that the conflict had firmly taken root in this volatile transboundary region.

Amid this already explosive environment, a deadly drone strike struck Tiné (Chad) on March 21, killing nearly two dozen civilians. Chadian authorities deny involvement, but accusations are mounting. Opposition leader Ousmane Dillo, currently exiled in Sudan, released an audio message across private networks, directly blaming Mahamat Déby and calling for his removal. He accuses Déby of endangering the Zaghawa community. On the Sudanese side, Darfur governor Minni Arkou Minawi took a dramatic step by declaring that “the war with Chad has already begun”, signaling a dangerous regional escalation.

Chad ramps up military presence at border

Chad’s government has doubled down on its stance of neutrality while signaling a firm response. Government spokesperson Gassim Chérif Mahamat reaffirmed Chad’s neutral position but warned of a “proportionate” retaliation against any attacks. President Mahamat Déby has since ordered the military to go on maximum alert. On March 22, a high-level security summit was held in Tiné, bringing together top military officials to strengthen border protection and prevent further destabilization. “This is Tiné, Chad—not Tiné, Sudan. Let the Sudanese army, the Toroboros, and the RSF fight it out in their own country. They must not bring their war here to kill our people,” declared General Ali Ahmat Akhabach, Minister of Security.

Following the summit, N’Djamena imposed a strict border closure, blocking civilians—especially women and children fleeing Sudan’s war—from seeking refuge in Chadian camps. While framed as a security measure to curb Zaghawa rebellion risk, the decision has drawn sharp criticism. Analysts, including Sudan conflict expert Cameron Hudson, warn that “Chad’s military buildup at the border risks dragging the country deeper into Sudan’s war instead of keeping it out. By projecting an image of strength, Déby may be making a grave strategic error.”

Ethnic tensions rise as Sudan war engulfs Chad

The Sudanese conflict is not just pulling the Zaghawa into its vortex. According to Chadian security sources, the RSF has been recruiting young men from the Tama community over recent weeks. This mobilization, bordering on mercenary activity, is being facilitated through local networks involving traditional leaders, administrative authorities, and figures close to the government.

Like the Zaghawa, the Tama are a transnational community, present in both eastern Chad (Wadi Fira, Ouaddaï) and western Sudan. Despite not being Arab, during the first Darfur war in 2003, they were integrated into the Janjaweed militias—the predecessors of Hemedti’s forces—and deployed against ethnic groups, notably the Zaghawa. This resurgence of old alliances is deeply concerning. It threatens to reignite long-dormant fractures within Chadian society and fuels fears of inter-community violence.

What was once a murky strategic calculation has now spiraled into a dangerous freefall. Chad’s government finds itself trapped in an escalation it may no longer be able to control. The genie is out of the bottle—and there’s no putting it back.
