Separate cross-border movement

Nearly 3,000
Reported arrivals
People reaching Djibouti over less than one week.

This arrival count measures movement across an international border. Published data do not show which, if any, of these people were also included in an internal-displacement snapshot.

Reporting cutoffs end September 18, 2026. Tracking systems may record movement after it occurs, so changes between snapshots do not establish the exact day each person moved.
