Pakistan has warned Iran to restrain its Houthi allies after attacks on Saudi Arabia wounded 73 people, while Saudi and Iraqi officials say Houthis helped Iran-backed Iraqi militias plan and execute a two-day drone swarm. The escalation has prompted Saudi-U.S. strikes, killed Iraqi fighters, Iranian advisers and a Houthi official, and intensified efforts by Saudi Arabia, Pakistan and Turkey to defend Saudi territory without entering Yemen. Iran says it does not control the Houthis, although Iranian sources said Tehran instructed the group to attack Saudi Arabia and supplied funding, weapons and coordination support. The confrontation is threatening Gulf shipping and global energy supplies as Washington maintains pressure on Iran and Qatar explores renewed negotiations.
