SANAA, April 24 (Xinhua) -- Yemen's Houthi rebels said that they launched a drone attack on Wednesday on a gathering of Saudi soldiers in the Saudi southern province of Asir.

"The drone strike hit the gathering of Saudi army in Rabuah area, killing dozens," rebel TV al-Masirah reported.

Meanwhile, Saudi-owned Al Arabiya television said that the Saudi-led coalition's warplanes launched a series of airstrikes on telecommunications rooms run by Houthi rebels in Eraij mountains in the Yemeni northern province of Saada and destroyed them.

Saudi-led military coalition intervened in Yemen in March 2015 to support President Abd-Rabbu Mansour Hadi after Houthi rebels forced him into exile and seized much of the country's north, including the capital Sanaa.

The coalition has been targeting the drone and missile capabilities of the Iran-allied Houthi rebels for years.

On Monday, the rebels threatened to launch long-range ballistic missiles against the Saudi capital Riyadh and the United Arab Emirates if they support attack on Yemen's rebel-held Hodeidah port city, a lifeline entry of commercial imports and humanitarian aid to rebel-held territory.

Forces of the Yemeni legitimate government backed by the coalition have advanced to the southern outskirts of Hodeidah since June 2018, but halted their major offensive to pave the way for UN-brokered peace efforts to end Yemen's four-year war.

A peace deal reached in Sweden in December last year has hit a deadlock after the rebels refused to withdraw from the port city.
