ISLAMABAD: Pakistan’s UN Ambassador Iftikhar Ahmad this week expressed alarm as the Russia-Ukraine conflict intensifies, calling for an immediate ceasefire and demanding both countries resolve their issues peacefully through dialogue. The development takes place days after Russia last week fired an intermediate-range hypersonic ballistic missile at Ukraine called Oreshnik. The move drew sharp criticism as the missile is capable of carrying nuclear and conventional warheads. Russia said it fired the Oreshnik in response to what Moscow says was an attempted Ukrainian drone attack on Dec.
