EU delays Sentinel imagery over Gaza

TLDR

• Bellingcat says free Sentinel-1 and Sentinel-2 imagery over Gaza and parts of the West Bank is delayed by 24 hours.¹
• An EU spokesperson told Bellingcat the delay aims to "mitigate possible threats" from the Middle East war, not Gaza.¹
• Bellingcat found four delayed regions since 2025; only the Gulf of Oman delay was referenced in an EU decision.¹

Bellingcat reported on 29 October that imagery from the European Space Agency's free Sentinel-2 (optical) and Sentinel-1 (radar) satellites appears to be delayed over Gaza and parts of the West Bank, based on its own analysis of image availability.¹ The delay is 24 hours. The affected tiles also cover parts of Israel and the Eastern Mediterranean Sea. Bellingcat dates the start of the delay to 28 March 2026.¹

Why it matters: free Sentinel imagery is the fallback many investigators use when commercial providers restrict access. Bellingcat gives a concrete case: imagery from 26 October that included Hebron would have helped confirm recent home demolitions, but the western half of the city was not available until 27 October.¹ Ars Technica reports that US firms Planet Labs and Vantor have largely restricted imagery tied to the Iran war, pushing journalists and researchers towards Copernicus data.³

Driving the news:

• An EU spokesperson told Bellingcat the delay was not related to events in Gaza but meant to "mitigate possible threats" from the war in the Middle East, including Iran's attacks on its neighbours and possible threats to European interests. The spokesperson said such decisions are taken unanimously by member states and stay in place as long as necessary.¹
• The spokesperson declined to say whether the delay relates to US vessels in the Eastern Mediterranean or whether other areas are delayed.¹
• Bellingcat identified four delayed regions in 2025 and 2026: the Gulf of Oman, the Gulf of Aden and western Arabian Sea, the Red Sea, and the Eastern Mediterranean region around Gaza.¹
• The delays came in stages. Researchers first saw 24-hour Sentinel-2 delays in March and April 2025, after the US campaign against Houthi targets in Yemen. The Gulf of Oman delay began on 15 July 2026.¹
• Sentinel-1 radar imagery is also delayed in the Gulf of Oman and Eastern Mediterranean regions, but not in the 2025 Red Sea and Gulf of Aden regions.¹
• The method is checkable: tiles in the Copernicus Data Space Ecosystem are listed through APIs that give each tile's capture and publication time, so the gap between the two shows the delay.¹

The big picture: the Gulf of Oman delay was the first one made public. Ars Technica, relaying SpaceNews, says a Council of the EU decision of 13 July ordered the 24-hour delay after a US request first made on 26 May.³ SpaceNews reported on 24 July that the delay covers some Sentinel-1 and Sentinel-2 imagery and followed a US request citing a security risk.² Bellingcat says the EU later issued a corrigendum that unpublished the decision (2026/1716) and removed it from the Council record, although the satellite data shows the delay stayed in place.¹ Bellingcat adds that the region named in that decision covers only part of the delayed tiles.¹ Ars Technica notes that a 24-hour delay is less onerous than the commercial restrictions, but still adds friction to timely reporting.³

The other side: the EU says the delay is a security measure and is not linked to Gaza.¹ The reason for choosing this region is unclear, because the spokesperson declined further comment.¹ "Appears to be delayed" is Bellingcat's inference from catalogue timestamps, not an EU announcement.¹

Single-source note: the Eastern Mediterranean delay, its 28 March start date and the list of four regions rest on Bellingcat's analysis alone. No EU document covering this region had been found at the time of writing, and the catalogue data was not independently re-run. The July background comes from SpaceNews and Ars Technica, and the SpaceNews piece was not read in full.
