Tehran:Iran's Supreme Leader Ayatollah Seyyed Ali Khamenei on Friday vowed: "tough revenge" on the US after an attack ordered by American President Donald Trump killed Gen Qassem Soleimani, the head of Iran's Islamic Revolutionary Guard Corps' (IRGC) elite Quds Force, in Iraq.
In a statement Khamenei said that the "cruelest people on earth" assassinated the "honourable" commander who "courageously fought for the year against the evils and bandits of the world", reports the Tehran-based Press TV.
"His demise will not stop his mission, but the criminals who have the blood of General Soleimani and other martyrs of the Thursday night attack on their hands must await vigorous revenge."
"... The continued fight and achievement of the final victory will make life bitterer for the murderers and criminals," he added.
