Violent clashes between protesters and security forces in the Pakistani port city of Karachi left at least nine people killed and more than 50 others wounded on Sunday, after hundreds of demonstrators attempted to storm the U.S. Consulate, authorities said.

The violence came hours after the United States and Israel attacked Iran and killed the country’s supreme leader, Ayatollah Ali Khamenei. Police and officials at a hospital in Karachi said that at least 25 people were also wounded in the clashes and some of them were in critical condition.

Summaiya Syed Tariq, a police surgeon at the city’s main government hospital, confirmed that initially six bodies and multiple injured people were brought to the facility. However, she said the death toll rose to nine after three critically wounded people died.
