Tehran(ANN)-Iran’s supreme leader, Ayatollah Ali Khamenei, described on Friday that the Iranian attacks on the US airbases in Iraq were “a slap in the face” for the US, international news agencies reported.

In the Friday khutbah, Khamenei’s first since 2012, he announced that Iran’s ability to respond to US attacks means that it has power from God.

“The fact that Iran has the power to give such a slap to a world power shows the hand of God,” declared Khamenei, according to Al Jazeera. He added that the US killing of Iranian commander, Qassem Soleimani, showed its “terrorist nature”.

Responding to Khamenei’s remarks, US President Donald Trump tweeted: “He should be very careful with his words.”
