The resolution which was passed by show of hands on Thursday also urged all sides to end the Yemen war which started in 2015 to restore its Saudi-allied former authorities, Press TV reported.
The coalition and the forces loyal to the ex-Yemeni officials “have been accused of shelling highly populated areas, including hospitals, schools, and other civilian targets,” the European Parliament said in a statement as published on its website.
“The MEPs call on all parties to the conflict to cease hostilities immediately,” the statement added.
“They strongly condemn the ongoing violence, attacks on civilians and demand that independent investigations into alleged human rights abuses and humanitarian law violations should be carried out.”
The resolution backs the United Nations, the European Union and efforts by member states to help end the conflict and provide support to those affected by it. “Only a political, inclusive and negotiated solution to the conflict can restore peace and preserve the unity [...] of Yemen,” the statement added.
Meanwhile, MEP Angela Vallina said the resolution “was directed at certain EU countries which do not yet respect this measure: For example, the UK, France, Sweden or Spain.”
“Airstrikes and lethal weapons against civilians have been used daily and have already caused thousands of deaths as well as the suffering of millions more from extreme famine,” Vallina concluded.
The US and the UK back the Saudi-led alliance in its war on Yemen which has killed more than 15,000 people, providing it with various types of support, including bombing coordinates, logistical provisions and aerial refueling.
The largest arms suppliers to Riyadh are the US with $8.4 billion worth of sales since 2014, followed by the UK ($2.6 billion) and France ($475 million).
Back in 2016, the European Parliament had passed another resolution through which it had demanded the imposition of an arms embargo on Saudi Arabia as long as it spearheaded the war on Yemen.
The head of the United Nation’s investigation team on the Yemen war accused Saudi Arabia and the UAE of hindering its work on documenting evidence of “possible war crimes” they have committed throughout their military aggression against the impoverished country.
Speaking to Al Jazeera on Thursday, Kamel Jendoubi said his panel had presented a list of human rights abuses to the UN, following a report in August that pointed to a “substantial number of violations of international humanitarian law” in the Saudi-led war.
Saudi Arabia and its allies have been critical of the UN panel’s work.
"I did not expect such a harsh reaction, we've done a professional, neutral and objective job," Jendoubi told Al Jazeera.
"All we did was report based on allegations and actions we collected during our visits, from testimonies and reports... It's a normal process for any experts," he said.
The August report blamed airstrikes by the Saud-led military coalition as the most direct cause of civilian casualties in the war.
Jendoubi’s report also mentioned a long-running blockade of Yemeni ports and airspace by the Riyadh regime and its allies as a possible violation of international humanitarian law.
