Cross-border attacks by Iran-aligned Houthi forces have increased since late May, when the coronavirus virus epidemic has ended. In late June, the missiles reached the Saudi capital of Riyadh. The coalition has avenged airstrikes.
Iran-aligned Houthis-run Al Masirah TV said on Sunday that Saudi-led coalition airstrikes had damaged fuel tanks at a factory in the Houthi-held region.
On Thursday, the coalition said it had intervened and launched an armed drone and two ballistic missiles towards southern Saudi Arabia.
Yemen has been engulfed in conflict since the Yemeni government was ousted from power in March 2015 by a Saudi government-led coalition to oust the government in the capital Sanaa. The Houthis say they are fighting a corrupt system.
