U.S. Secretary of State Antony Blinken said Wednesday that the United States was "not aware of or involved in" the killing of Hamas's political leader, Ismail Haniyeh, in Iran. 

"I can't tell you what this means. I can tell you that the imperative of getting a ceasefire, the importance that that has for everyone, remains," Blinken said in an interview with Channel NewsAsia in Singapore. "This is something we were not aware of or involved in," he said of the killing.
