The blasts damaged two houses, authorities said in a statement, without adding further details.

Morocco considers Western Sahara as its own territory, but the Algerian-backed Polisario Front wants an independent state there.

In November 2020, Polisario said it had resumed its armed struggle.

Most of the fighting was described by the United Nations as “low intensity”, and occurring mostly in the uninhabited eastern part of the Morocco-built security wall.

Morocco has said autonomy is the most it can offer to the territory as a political solution. The Polisario and its ally Algeria are demanding an independent state.

The UN Security Council has urged the parties to the conflict to seek a mutually acceptable solution.

Israel was the latest country to recognise Morocco’s sovereignty over the territory in July, a move the US took in 2020.

Twenty-eight other countries – mostly African and Arabian – have opened consulates in Dakhla or the city of Laayoune, in what Morocco sees as tangible support for its Western Saharan rule.
