President Emmanuel Macron on Tuesday defended French weapons sales to the Saudi-led coalition fighting in Yemen, but said he was concerned by the humanitarian situation and would host a conference on the issue before the summer.

Pressure has been mounting on Macron to scale back arms support for Saudi Arabia and the United Arab Emirates (UAE), which are leading the coalition fighting the Iran-aligned Huthi group that controls most of northern Yemen and the capital Sanaa.

The conflict has killed more than 10,000 people and displaced more than 3 million, with no sign of a diplomatic breakthrough to ease the crisis.

Seventy-five percent of French people want Macron to suspend arms exports to Saudi Arabia and the UAE, a YouGov poll found. Several rights groups also have warned of possible legal action if the government does not halt its sales.

"Since the start of the conflict in Yemen, France has adopted a very specific process whereby all sales of military equipment are analysed on a case-by-case basis and on the basis of reinforced criteria that reflect respect for international humanitarian law and the risk of harm to civilian populations," Macron said at a news conference alongside Saudi Crown Prince Mohammed bin Salman.

"France's position is clear: full support for the security of Saudi Arabia, condemnation of the ballistic activity coming from the Houthis, willingness to find a political solution to the conflict and strong humanitarian demands on civilian populations," Macron said.
