Pakistan recalled its ambassador to Tehran on Wednesday, a day after Iran launched airstrikes on Pakistan that it claimed targeted bases for a militant Sunni separatist group.

Islamabad angrily denounced the attack as a “blatant violation” of its airspace and said it killed two children.

Tuesday's strike on Pakistan's restive southwestern Baluchistan province imperiled diplomatic relations between the two neighbors, but both sides appeared wary of provoking the other.
