"Yemeni drones and robots strike the Saudi enemy," it was reported on Telegram.
Another post states that attacks hit an airport, an air base and facilities belonging to the oil company Aramco.
Saudi Arabia has not commented on the information.
More than 300 people have been killed in fighting between the Houthi movement and Yemen's Saudi-backed government forces since Thursday, when the Houthi movement launched an offensive to try to surround the government-controlled port city of Mocha.
The rebels are also trying to advance towards areas along the coast at the Bab al-Mandab Strait, the southern gateway to the Red Sea.
The waterway has become increasingly important since traffic in the Strait of Hormuz was blocked due to the Iran war.
