The Arab coalition warplanes carried out airstrikes and targeted a base of Yemen's Republican Guards forces controlled by Houthis in the Red Sea coast city of Hodeidah on Tuesday.
According to Xinhua a number of airstrikes targeted a base of the elite Republican Guards forces, causing huge blasts amid reports of casualties among the rebels.
A military official told Xinhua on condition of anonymity.
The official of the pro-government Giants Brigades said that "Houthi operations rooms located inside the base might be destroyed during the aerial bombardment."
There are no immediate reports about the exact number of casualties as Houthi rebels surrounded the bombing site and prevented local people from access.
The warplanes kept hovering over the city's airspace providing aerial support for the Yemeni government forces advancing against Houthis in Hodeidah, according to the official.
The agency also said that residents near the scene confirmed by phone saying that the base used by the Iranian-backed Houthi rebels was hit several times in the previous hours and ambulances rushed to the targeted site.
