China urged Pakistan and Iran on Wednesday to show "restraint", after Islamabad said Tehran had carried out an air strike on its territory that killed two children. "We consider both Iran and Pakistan as close neighbours and major Islamic countries," she said. Both Iran and Pakistan are close partners of Beijing and members of the Shanghai Cooperation Organisation. Pakistan denounced the strike, near the nations' shared border late on Tuesday, as "completely unacceptable", saying it was unprovoked. “It is even more concerning that this illegal act has taken place despite the existence of several channels of communication between Pakistan and Iran,” the FO said.
