Unprovoked aggression or spillover... into Saudi Arabia will definitely make this agreement operational."The Pakistani defense ministry, foreign ministry and the military did not respond to a Reuters request for comment.Pakistan’s intervention, after years of balancing ties with Saudi Arabia and Iran, has underscored the seriousness of the Houthi attacks. The message to Tehran is clear: rein in the Houthis or risk turning a proxy conflict into a broader regional security crisis, the sources said.A senior regional diplomat said Pakistan had conveyed the message to Iran over the past 24 hours, urging Tehran to use its influence to halt Houthi attacks on Saudi ​Arabia.A senior Iranian official confirmed that Pakistan conveyed the message to Tehran on Tuesday and Tehran's response was that "Iran does not control the Houthis."Fighters loyal to the Saudi-backed Yemeni government forces at a checkpoint near Hodeidah amid renewed fighting in Yemen against the Houthis(Photo: Khaled Ziad / AFP)However, two Iranian sources said Tehran had told the Houthis last ​week to carry out attacks on Saudi Arabia. Tehran promised additional funding and weapons, they said, while several Islamic Revolutionary Guard Corps commanders had travelled to Yemen to help coordinate the attacks.The regional diplomat said Islamabad was ‌seeking to ⁠restrain the Houthis before the escalation reached a point where Riyadh could press Pakistan to play a more active role in defending it."Pakistan has an agreement with Saudi Arabia, but I am hopeful the situation will not reach the point where Pakistan has to practically step in," the diplomat told Reuters. "It will pursue a diplomatic solution for now."The Pakistani source said Saudi officials had met senior Pakistani and Turkish military representatives in Riyadh to coordinate their response. The three countries agreed that their troops would not enter Yemen and that any response would be launched from Saudi territory, the source added.A ​second Pakistani source said no decision had been ​made to join retaliatory strikes, stressing that ⁠its military pact with Riyadh was defensive and limited to protecting Saudi territory. Pakistani forces could provide military, technical, ground or air support within Saudi Arabia, but would not take part in combat operations on foreign soil, the source said.The pressure campaign waged by Iran and the Houthis could have the ​opposite effect to that intended by Tehran, the regional diplomat said.By targeting Gulf security in a bid to pressure Washington over its blockade of ​Iranian ports, Tehran risks driving ⁠Saudi Arabia, Pakistan, Turkey and other U.S.-aligned states into closer security coordination rather than fracturing their ties.Regional officials also see little sign that Washington is prepared to relent.President Donald Trump appears committed to maintaining the U.S. blockade until Iran reaches an agreement with Washington, the diplomat said, while Qatar is quietly exploring new proposals aimed at bringing both sides back to negotiations.Another regional source said Saudi ⁠Arabia's military response ​would remain focused on the Houthis rather than Iran itself. Nor do Saudi officials believe Houthi attacks will achieve Tehran's ​broader objective of ending the U.S. blockade.Riyadh is not expected to press Washington to lift the blockade, that source said, stressing that Trump believes sustained economic coercion is the most effective pathway to negotiations."The question is how much pain Iran can absorb, ​and for how long," the source said. "Trump does not want a military solution. He wants to squeeze them through the blockade."
