The leader of the Syrian National Council, an opposition group, has brought his call for arms to the European Parliament.
Ahmed Jarba told MEPs at a hearing in Brussels that his group needed arms to fend off attacks from the Assad regime.
He was speaking three years on from the start of the Syrian conflict.
“We are asking for weapons, not direct military intervention as that is not possible. We need specific weapons to take down the Syrian air force,” said Jarba.
“That’s what we want so that the regime’s air forces are taken out and so that things can evolve and change naturally.”
More than 146,000 people have died since the country’s civil war broke out in March 2011, according to the Syrian Observatory for Human Rights.
The UN stopped updating its own death toll in January, saying such information was too difficult to verify.
