An investigative website claims French weapons have potentially been used by Saudi Arabia and the United Arab Emirates in Yemen's war.

Disclose based its report on an October 2018 classified note from France's military intelligence service, saying Monday that French-made weapons including artillery, tanks, ships and fighter-bomber jets "may have been used to commit war crimes."

The Arab military coalition has fought Yemen's Houthi rebels since 2015 in a conflict that has killed tens of thousands of people.

The French government did not immediately respond to an email seeking comment. France previously said its weapons were only used defensively.

Reacting to the report, Amnesty International urged France "to immediately suspend all arms transfers that could be used by any of the warring parties in Yemen - once and for all."
