Tehran: Iran on Friday vowed to take a "vigorous revenge" over the killing of General Qassem Soleimani, the head of Iran's elite Ayatollah Ali Khamenei (IRGC). Iranian Leader Ayatollah Ali Khamenei paid a tribute to Soleimani as a "martyr" and announced three-day national mourning in the country, reported Al Jazeera. Iran Foreign Minister summoned the Swiss Charge d'affairs to Tehran, the US interest section in Iran, to convey protest against US' "terrorist" act. Iran Foreign Minister Javed Zarif took to Twitter soon after Pentagon confirmed the killing of Soleimani. He said that Washington bears responsibility for all consequences of its "rogue adventurism".

The Green Zone in Baghdad was completely locked down by Iraqi security forces to prevent any emergency following the strike, two Iraqi security officials told CNN. "The US' act of international terrorism, targeting & assassinating General Soleimani--THE most effective force fighting Daesh (ISIS), Al Nusrah, Al Qaeda et al--is extremely dangerous & a foolish escalation. The US bears responsibility for all consequences of its rogue adventurism," Zarif tweeted.
