Sudan and Chad: a closed border and growing suspicions weakening N’Djamena

The ongoing war in Sudan is fueling a humanitarian emergency of epic proportions. In this latest Sahel analysis English, we look at how nearly a million refugees have flooded into Chad, a nation now standing on the precipice following the fall of El-Fasher in North Darfur. Within a mere two weeks, roughly 100,000 civilians abandoned the city, with about 6,000 of them crossing into Chadian territory. This critical influx is overwhelming a country already burdened by decades of regional volatility.

A strategic frontier under immense strain

The 1,300-kilometer boundary separating the two countries consists of vast desert stretches that are nearly impossible to monitor effectively. Traditionally a transit point for various insurgencies, these areas are currently jeopardized by the advances of the Rapid Support Forces (RSF), who now dominate the majority of Darfur. This shift in West Africa insider news highlights a dangerous escalation in regional insecurity.

Military friction has intensified since December 2024. A drone attack resulted in the deaths of two Chadian soldiers, while a January 2025 incursion linked to the RSF near Tiné claimed seven lives. In response to these provocations, N’Djamena has completely obstructed its border, citing the imminent risk of the Sudanese conflict bleeding into its own lands.

<h3><strong>Official neutrality versus persistent allegations</strong></h3>

<p>The government of Chad maintains that it is a neutral observer in the Sudanese civil war. However, investigative reports and satellite data suggest that military hardware from the United Arab Emirates may have transited through Chad to supply the RSF. While N’Djamena categorically denies these reports—pointing to the fact that it has been a target of cross-border strikes—the suspicions linger.</p>

<p>These tensions are creating internal fractures within the Chadian state. In April 2025, several senior military officers were purged, particularly those from the Zaghawa ethnic group. This group holds significant influence within the security apparatus and has a history of deep-seated opposition to the RSF.</p>

<h3><strong>A diplomatic pivot toward France</strong></h3>

<p>Following a period of strained diplomacy, the Chadian leadership is once again seeking a closer relationship with Paris. In the broader landscape of <strong>Sahel politics</strong>, the crisis in Sudan has become a central pillar of the dialogue between Mahamat Idriss Déby and Emmanuel Macron.</p>

<p>Historically, France provided essential intelligence support that was vital for securing the border. As that assistance waned, N’Djamena now views a diplomatic thaw as a strategic priority to safeguard its sovereignty.
