Pact declares any attack on Saudi Arabia or Pakistan an attack on both, deepening shared security alliance.

Saudi Arabia and nuclear-armed Pakistan have signed a formal mutual defence pact, state media from both countries said, in a move that significantly strengthens a decades-long security partnership.

“This agreement, which reflects the shared commitment of both nations to enhance their security and to achieving security and peace in the region and the world, aims to develop aspects of defense cooperation between the two countries and strengthen joint deterrence against any aggression. The agreement states that any aggression against either country shall be considered an aggression against both,” a joint statement published on Wednesday said, according to the Saudi Press Agency.
