Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei slams the US and its elements for conducting terrorist attacks against Iranians in the past.

In an address to the families of Iranian martyrs in Tehran on Saturday, the Leader said the shooting down of a passenger plane in 1988 was one of the US acts of terror against Iran.

Ayatollah Khamenei said knowing one's enemies is one of the crucial requirements of the current era and warned against attempts to whitewash the crimes of the enemies.

"Those who want to cover up the evil enmity of the US and and some of its followers through media and propaganda ploys are in fact betraying the nation and state," the Leader said.

"The Iranian nation should through awareness of the extent of the enemy's hostility be prepared to confront and counter [its plots] in the soft war arena, such as in cultural, political and social spheres," the Leader said.
