A rights group filed a lawsuit against Saudi Crown Prince Mohammed bin Salman during his visit to France on Tuesday, accusing him of complicity in torture and inhumane treatment in Yemen, lawyers said.

The complaint on behalf of Taha Hussein Mohamed, director of the Legal Center for Rights and Development (LCRD), said the prince who is Saudi Arabia’s defence minister was responsible attacks that hit civilians in Yemen, Reuters reported.

The case was filed in a Paris court as pressure grows on President Emmanuel Macron to curb arms sales to Saudi Arabia and the United Arab Emirates, which spearhead a coalition fighting Iran-aligned Houthi rebels who control of most of northern Yemen and the capital Sanaa.

Speaking to reporters in Paris, Foreign Minister Adel al-Jubeir dismissed the lawsuit and said the Houthis should be held accountable for the war in Yemen.
