RIYADH: The coalition destroyed and explosive drone launched from Sanaa airport, the Saudi Press Agency reported.
The drone was downed in the governorate of Amran in Yemen.
The coalition also hit Houthi units, who they said were moving weapons.
The drone was assembled and rigged by the Houthi air defense unit at the airport, the coalition said.
Saudi Arabia’s air defenses often destroys the militia’s drones, which are launched from northern Yemen.
In a separate incident reported early Wednesday, the coalition destroyed an explosive-ladened boat in the Red Sea, saying the vessel set sail from Hodiedah governorate.
They said the Houthis’ threat to freedom of navigation at sea endangers regional and international security.
On Tuesday, the coalition hit Iranian Revolutionary Guard experts in Yemen’s capital.
The operation complies with international humanitarian law and its customary rules, the coalition said.
The coalition has hit a number of sites in the capital in the past few weeks in an effort to deteriorate the capabilities of the Iran-backed Houthi militia.
Houthi attempts to target civilians has been labeled as war crimes by the Kingdom.
The coalition has been supporting the internationally recognized Yemeni government regain full control of the country after the Houthis seized the capital, Sanaa, in 2014.
The war, which has now lasted for seven years, has cost thousands of Yemenis their lives and has forced many more to depend on humanitarian assistance.
