On the news front, Rashad al-Alimi, chairman of Yemen's Presidential Leadership Council, who exercises presidential powers, delivered a televised speech on October 4, announcing the launch of a "major military operation" against the Houthi armed group in Yemen to seize territory under its control. Al-Alimi said the decision to launch the counteroffensive was made after "all opportunities for de-escalation had been exhausted," and he accused the Houthis of responding to efforts to ease the conflict with further escalation. In his televised address, he said: "Today, I announce the start of military operations to recover territory and extend the authority of the state and its institutions across the entire homeland."

According to people familiar with the matter, in this military operation, Saudi Arabia will lead the air campaign, while Yemeni government forces will be responsible for ground combat. The United States is providing intelligence support for Saudi operations in Yemen, and some regional countries and European countries are mainly providing defensive military assistance to Saudi Arabia. The command headquarters of the Saudi-led multinational coalition issued a statement saying the coalition will continue to provide comprehensive operational support to the Yemeni government and its armed forces in order to "restore the state."

Coalition spokesman Turki al-Maliki accused the Houthis of deliberately and systematically attacking civilians and civilian facilities in multiple Saudi cities including Riyadh, and also attempting to attack the cities of Mecca and Medina, as well as trying to attack Saudi ships in the southern Red Sea and the Bab el-Mandeb Strait. He said the coalition will continue to take necessary measures to curb the Houthis' hostile actions and safeguard Saudi Arabia's security and sovereignty. Al-Maliki stressed that Saudi Arabia will take relevant operational measures to respond to Houthi attacks and eliminate threats to freedom of navigation in the southern Red Sea and the Bab el-Mandeb Strait. He said such threats not only endanger regional and international security, but also threaten international trade, the global economy, and the interests of all countries.

Yahya Saree, spokesman for the Yemeni Houthi armed group, said in a video statement on October 4 that over the past 12 hours, Saudi Arabia launched 50 airstrikes and missile attacks on Yemen's capital Sanaa and the provinces of Al-Jawf, Taiz, Amran, Hodeidah, and Saada — since the current round of escalation began in early September, Saudi Arabia has carried out a cumulative total of 1,460 airstrikes and missile attacks on Yemen. Saree said that in retaliation, the Houthis used missiles and drones that day to attack Saudi Aramco oil facilities in the Saudi capital Riyadh and the Khurais area, and claimed the attacks "successfully hit their targets." Saree said the Houthis will continue to use Yemen-made missiles and drones to attack Saudi military bases and oil facilities until Saudi Arabia stops its military operations and lifts the blockade on Yemen.

In addition, on October 4, Iranian Parliament Speaker Mohammad Bagher Ghalibaf said that in the face of Iran's resistance and firm stance, the United States has fallen into a state of desperation. Ghalibaf said that although the United States has a different narrative, recently the US side has put forward some proposals through intermediaries. The United States must realize that the era of imposing unilateral demands through a war of attrition is gone forever. Iran's position is clear and firm, namely that the Strait of Hormuz will never be opened before Iran's seven conditions based on the Islamabad Memorandum of Understanding are met.

According to Iran's Fars News Agency on October 4, Iranian military spokesman Akraminia said the Iranian military has decided to begin increasing the range of its missiles. In an interview with the agency, Akraminia said the reason for this decision was that Iran had drawn "lessons" from its conflict with the United States and Israel. "In this conflict, we concluded that we must increase the missile range, and we have now embarked on this path," he said. Akraminia also said that the "enemy" has deployed troops and warships "farther from Iran's coast," up to 1,000 kilometers away, so Iran "will continue to upgrade its missiles." He also stressed that Iran has made significant progress in improving missile speed and accuracy.
