The Saudi-led coalition fighting rebels in Yemen says Saudi air defense units have intercepted a rocket fired from inside Yemen in the southwest border city of Jazan.

A statement by the coalition said the rocket, which was fired early Monday, did not cause injuries or material damage and that the Saudi Air Force reacted immediately and destroyed the launching pad inside Yemen.

A Saudi-led coalition has been targeting Shia rebels in Yemen, known as Houthis, since late March. Cross-border shelling has killed Saudi border guards and soldiers amid the campaign.

International aid groups say Yemen's war has killed up to 2,000 people and wounded 8,000. The U.N. estimates at least 1,037 civilians have been killed.
