Saudi Arabia has been accused of bombing civilians with European-made equipment during in its war in Yemen.
The European Parliament has voted in favour of an EU-wide embargo on selling arms to Saudi Arabia.
A resolution calling for a ban on all weapons sales to the country was passed by 359 votes to 212, with 31 MEPs abstaining.
The non-binding motion calls on member states to stop selling weapons to the country, which is currently conducting a widely-criticized military operation in neighboring Yemen marked by high civilian casualties.
Saudi Arabia is intervening in Yemen to fight Houthi rebels, who control the country’s capital but are not internationally recognized as its government.
Criticism of the country’s military operation have however included the bombing of multiple hospitals run by the charity Medicines Sans Frontiers and the deaths of thousands of civilians, including 130 at a single wedding.
While international observers have recognized abuses on all sides, in late December UN human rights chief Zeid Raad al-Hussein said that a “disproportionate” number of attacks of civilians in Yemen had come from the Saudi-led invasion force.
