According to CCTV News, Yahya Sarea, military spokesman for Yemen's Houthi rebels, announced on the 4th local time that the group launched missile and drone attacks on two Saudi Aramco facilities in Riyadh and Khurais. In the early morning of the 6th local time, loud explosions were heard again in Riyadh, the capital of Saudi Arabia, following explosions in Riyadh on the evening of the 5th. The Houthi rebels stated in a declaration on the night of the 5th that in response to Saudi Arabia's military operations in the past 24 hours, they carried out three rounds of military operations that day, using a large number of ballistic missiles, cruise missiles, and drones to attack multiple targets, including King Khalid International Airport in Riyadh and the Rabigh Aramco refinery.

Meanwhile, according to Xinhua News Agency, Rashad al-Alimi, chairman of Yemen's Presidential Leadership Council, announced on the 4th that the Yemeni government has officially launched a large-scale military operation to retake areas recently controlled by the Houthi rebels. Saudi-backed Yemeni government forces, under the cover of the Saudi air force, launched attacks on Houthi positions near the Bab al-Mandab Strait. The Houthi rebels also occupied Turabah, a strategic location in southern Taiz province, which could cut off government supply lines. A full-scale exchange of fire has formed between the two sides, and the security risks to Red Sea shipping and energy export channels have sharply increased, putting upward pressure on international oil prices.
