Three years into Sudan’s brutal civil war, its deadly consequences have now spilled across the border into Chad. Cross-border strikes, rising military tensions, and deepening communal rifts are pulling N’Djamena into a conflict it once sought to avoid.

Chad’s precarious balancing act

Since April 2023, Sudan has been torn apart by war between General Abdel Fattah al-Burhan’s Sudanese Armed Forces and the Rapid Support Forces (RSF) led by Mohamed Hamdan Dagalo, known as Hemedti. While Chad has publicly maintained a stance of neutrality, its covert support for the RSF has sparked intense debate. This backdoor alliance places President Mahamat Déby’s government in a dangerous bind: backing a force accused of targeting the Zaghawa community—an ethnic group deeply embedded in Chad’s political and military elite. Weapons shipments, reportedly funded by the United Arab Emirates, have reportedly passed through border towns such as Amdjarass and Adré, a gamble that has now come back to haunt Chad.

Tiné: a flashpoint on both sides of the border

Tiné exists on both sides of the Chad-Sudan frontier, straddling the same Zaghawa-dominated communities. For years, it has served as a critical crossing point for civilians fleeing the horrors of Darfur’s violence. But on February 21, 2026, the RSF seized control of the Sudanese side, immediately clashing with Toroboro fighters—Chadian and Sudanese militias allied with General al-Burhan—as well as unofficially deployed Chadian troops. Within days, the city was recaptured. In response, N’Djamena announced the closure of the border, yet fighting persisted, underscoring how deeply the conflict had already taken root in this transborder space.

On March 21, 2026, a deadly drone strike struck Tiné in Chad, killing more than two dozen civilians. While Chadian authorities deny involvement, accusations have flown fast. Exiled opposition leader Ousmane Dillo, currently based in Sudan, released an audio message widely circulated across private messaging platforms, directly blaming Mahamat Déby and calling for his removal. He also accused the president of endangering the Zaghawa community. Across the border, Sudan’s Darfur governor, Minni Arkou Minawi, escalated rhetoric by declaring « the war with Chad has already begun », signaling a dangerous regional escalation.

N’Djamena’s firm stance amid rising threats

Chadian officials have doubled down on their narrative of neutrality while signaling a willingness to respond with force. Government spokesperson Gassim Chérif Mahamat reaffirmed Chad’s neutral position but warned of a « proportional response » to any aggression. In a show of force, President Mahamat Déby ordered the military to a state of maximum alert. On March 22, a high-level security summit in Tiné brought together top military commanders to bolster border security and preempt any destabilization within Chad. « 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 ban on civilian crossings at the border, preventing women and children fleeing Sudan’s war from reaching refugee camps in Chad. While framed as a preventive measure against potential Zaghawa unrest, the move has drawn sharp criticism. Analysts warn this hardline approach may backfire. « Chad’s military buildup along the Sudanese border amid rising tensions risks drawing Chad deeper into the Sudanese conflict rather than keeping it out. Déby’s attempt to project strength could prove a costly strategic misstep », cautioned Cameron Hudson, a leading expert on the Sudanese conflict.

Communal fault lines widen as war spills over

The spillover is not limited to the Zaghawa. According to Chadian security sources, the RSF has been actively recruiting young men from the Tama community—another transborder group with presence in eastern Chad (Wadi Fira, Ouaddaï) and western Sudan. During the 2003 Darfur conflict, some Tama factions were integrated into Janjaweed militias—precursors to the RSF—and engaged in violence against ethnic groups including the Zaghawa. This resurgence of old tensions is stoking fears of renewed communal fractures within Chad and fueling inter-community distrust.

What was once a calculated, if ambiguous, strategic posture is now unraveling into a perilous overreach. Chad’s government finds itself ensnared in a conflict it may no longer be able to control. The genie is out of the bottle—and it’s not going back in.
