Islamabad, March 1 Pakistani Prime Minister Shehbaz Sharif expressed concern over "violations of international law norms" following the killing of Iran's Supreme Leader Ayatollah Ali Khamenei in a joint attack by the US and Israel.
In a social media post, the Pakistani prime minister said, "The government and the people of Pakistan join the people of Iran in their hour of grief and sorrow and extend the most sincere condolences on the martyrdom of Ayatollah Seyyed Ali Khamenei."
He expressed Pakistan's concern over "violations of international law norms."
The prime minister stated that it is a long-standing convention that heads of state and government should not be targeted.
Separately, President Asif Ali Zardari in a statement "conveyed heartfelt condolences to the Government and the people of Iran."
"Pakistan stands with the Iranian nation in this moment of grief and shares in their loss," he said.
He said that "the passing of a leader of such stature, along with other senior figures, would be deeply felt across the Muslim world."
Meanwhile, at least 10 people were killed in firing when protesters tried to storm the US Consulate in Karachi as violent clashes and arson rocked different cities of Pakistan on Sunday over the killing of Khamenei.
Khamenei was killed on Saturday in a coordinated US-Israeli airstrike on Tehran, with his death confirmed on Sunday, prompting an outburst of anger by Pakistan's Shiites, who are about 20 per cent of the 240 million population.
