Pakistan launched a tit-for-tat attack on Iran's Sistan-Balochistan province 24 hours after Tehran's missile and drone strikes in Balochistan. Tehran claims nine non-Iranians, mostly women and children, have been killed. Pakistan Army is on alert after both countries expelled their diplomatic representatives. What's interesting is that both Iran and Pakistan are singing similar tunes. Both say the action was against terrorist groups acting from across the border.
