A Spanish court has launched a new legal step over the detention of a Spanish peacekeeper in southern Lebanon, requesting clarification from the United Nations on whether an investigation into the incident had been opened.
Judge Antonio Pina of Spain’s National Court has formally asked the UN to confirm whether it is aware of the incident, whether it was raised with Israeli authorities, and whether any investigation has been initiated.
The request comes as the court considers whether to open a criminal probe into the case.
The move follows a request from prosecutors after a complaint was filed by the political group Iustitia Europa, which called for legal action against senior Israeli officials, including Prime Minister Benjamin Netanyahu and army chief Herzi Halevi, over potential violations of international law.
The case relates to an incident on 7 April, when Israeli forces stopped a logistics convoy belonging to the UN Interim Force in Lebanon (UNIFIL) in southern Lebanon. A Spanish soldier was detained for around an hour before being released without injury.
The incident triggered a strong response in Madrid at the time, with Spain’s foreign ministry summoning Israel’s envoy, Dana Erlich, to lodge a formal protest over the “unjustifiable detention” of a peacekeeper.
Spain’s Defence Minister Margarita Robles said the government had issued its “strongest protest” to both the United Nations and the Israeli government, after which the soldier was released. She added that Madrid had requested accountability and received assurances that those responsible would be punished.
According to Spanish officials, the convoy had been transporting food and supplies to another UNIFIL contingent when an Israeli patrol stopped it, and one soldier was held for a period before being freed.
The complaint before the Spanish court argues that the incident may constitute a violation of international humanitarian law and the protections afforded to peacekeeping forces, which are expected to operate without obstruction.
It also suggests that detaining a UN soldier, even temporarily, could amount to unlawful detention or coercion, and potentially rise to the level of a war crime if intent is established.
The court’s request to the United Nations is seen as a key legal step, tied to the principle of complementarity, under which national courts may defer to international investigations if one is already underway.
Based on the UN’s response, the judge will decide whether Spanish courts will proceed with their own inquiry, in a case that could take on wider political and diplomatic significance, particularly amid growing tensions between European countries and Israel over its military operations in the region.
It also comes as Israeli forces have carried out over a dozen attacks on UNIFIL peacekeepers in southern Lebanon since the war began in October 2023.
By March 2026, UNIFIL reported at least five peacekeepers killed in separate incidents in southern Lebanon and several more injured in convoy explosions and direct fire on patrols.
