ISLAMABAD: Pakistan on Sunday warned its citizens in the Middle East and Arabian Gulf states to exercise caution, avoid travel and strictly follow official adviseries, amid escalating tensions following the killing of Iran’s Supreme Leader Ayatollah Ali Khamenei in US–Israeli strikes.

Iranian state media reported that the 86-year-old was killed in an airstrike targeting his compound in downtown Tehran. The Iranian Revolutionary Guard warned of “a severe, decisive and regret-inducing punishment” coming over Khamenei’s killing.

Israel and Iran traded new attacks Sunday, after Tehran hit both the Dubai International Airport — the world’s busiest for international traffic — and Kuwait’s main airport during its retaliatory strikes one day earlier.

As Iran’s army announced strikes targeting US bases in the Gulf and Iraqi Kurdistan, Trump threatened to unleash “force that has never been seen before” and urged Iran’s people to rise up and seize power.

“In view of the evolving regional situation, the Ministry of Foreign Affairs has activated its Crisis Management Unit (CMU) to closely monitor developments and extend all necessary assistance,” the Pakistani foreign office said.
