An attack by the Houthis on southern Saudi ​Arabia wounded 11 civilians on Thursday, a military official said, as the Iran-aligned group escalates attacks on the Kingdom and in Yemen. Maj Gen Turki Al Maliki, spokesman for the Saudi-led military coalition supporting Yemen's internationally recognised government, said early Friday the attack in southern Najran Province injured seven Saudis, one Yemeni, two Egyptians and one Pakistani national. The victims included ⁠a 4-year-old child who suffered second-degree burns."The terrorist Houthi militia carried out these terrorist attacks using indiscriminate shelling against civilian objects," Maj Gen Al Maliki said, labelling the attacks as a violation of international law. He said the coalition would ‌continue taking all necessary measures to protect civilians.There was no immediate comment from the Houthis on the coalition's statement, but the group has increased attacks in recent weeks. Riyadh's decade-old conflict with the Tehran-aligned Houthis has become increasingly entangled with the wider war, as the group's actions, such as a Red Sea blockade that has disrupted Saudi oil exports, have raised the stakes of the broader regional confrontation.On Tuesday, the Houthis claimed to have attacked Saudi Arabia's Najran airport, part of a broader escalation in which they have struck military, infrastructure and shipping targets in the Kingdom. Their claims are often exaggerated. They also killed at least 45 Yemeni government troops earlier on Thursday in Marib and Hadhramaut provinces. The Houthi military spokesman Yahya Saree said the group attacked camps belonging to what it described as the Saudi-backed First and Third Emergency Divisions in Yemen, using ballistic missiles and drones.The Houthis claimed the attack killed and wounded hundreds of fighters and destroyed camps, weapons depots and military vehicles. It urged Yemeni fighters aligned with Saudi Arabia to leave their positions and return home.Saudi Arabia supports the Yemeni government. Conflict with the Houthis lessened following an agreement that was signed in 2022, but the rebels have escalated attacks against Saudi ships in the Red Sea and Saudi oil facilities in recent weeks.The Houthis say the attacks are in response to Saudi Arabia's “blockade” of Houthi-controlled areas, including ports and Sanaa International Airport.The Kingdom recently launched an international maritime alliance aimed at protecting the Red Sea and the Bab Al Mandeb - key lanes for Saudi exports - from Houthi attacks. On Thursday, the Saudi Defence Ministry announced that Maj Gen Abdullah Al Shehri had been appointed commander of the alliance.A senior Saudi official told Reuters that Saudi, US and other Middle Eastern countries' intelligence found that the Houthis and Iraqi militia groups, under the coordination of Iran's Islamic Revolutionary Guard Corps, could soon launch coordinated attacks on key civilian sites. The Kingdom has said that several attacks it has confronted since the start of the Iran war in February were launched from Iraqi territory. Last week, Saudi Arabia and the US conducted joint strikes on Iran-backed militias in Iraq. Riyadh is seeking to deepen security cooperation with key allies. Saudi Arabia already has a defence cooperation agreement with Pakistan.Pakistani Prime Minister Shehbaz Sharif arrived in ​the kingdom on Thursday, while Turkish President Tayyip Erdogan was due to arrive on ‌Friday for a meeting with Saudi Crown Prince Mohammed bin Salman.
