"Riots erupted in Karachi on Sunday, where a police armoured vehicle was set ablaze during violent demonstrations near the US Consulate-General. The unrest broke out after the killing of Iranian Supreme Leader Ali Khamenei in a joint US-Israeli strike. Footage shows flames tearing through the vehicle as thick black smoke billows into the sky. Officers responded with tear gas and baton charges in an attempt to disperse the crowds. Additional security personnel were deployed to secure the area as confrontations continued. According to reports, pro-Tehran protesters gathered near the diplomatic compound, with some breaching parts of the outer security perimeter. A police post and at least one vehicle were set on fire outside the main gate, triggering clashes with police and paramilitary forces. At least 10 people were killed, and dozens more injured in the clashes in Karachi, with the nationwide death toll reportedly exceeding 25 following similar demonstrations in Lahore, Islamabad and Peshawar. In response, the US Embassy in Pakistan issued a security alert urging American citizens in the country to remain vigilant and monitor local developments closely. Iranian state media reported the death of Supreme Leader Ali Khamenei during the attacks, prompting Tehran to declare 40 days of national mourning and a seven-day public holiday, with all government offices and schools closed as the country prepares for funeral rites. The United States and Israel launched a joint strike on Saturday, with US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu vowing to 'destroy Iran's missiles.' In response, Iran's Revolutionary Guard Corps said that 'widespread missile and drone attacks' against Israel were underway. US bases were also reportedly targeted in the UAE, Bahrain, Qatar, Iraq and Kuwait."
