About this, according to Mehr agency, Ayatollah said during the Friday prayer, which he personally held for the first time in eight years.
According to Khamenei, "the enemies were so happy about the unintentional crash of the plane," because they had the pretext "to blacken the face of Iran."
Earlier, foreign ministers of Canada, Ukraine, Sweden, Afghanistan and the United Kingdom called on Iran to pay compensation to the relatives of the dead passengers of the Ukrainian plane that was shot down over Tehran.
Ukrainian Boeing 737 of Ukraine International Airlines crashed on January 8 shortly after departure from Tehran. The victims of the crash were 176 people.
On January 11, Tehran admitted that the country's air defense system mistakenly shot down a passenger plane, mistaking it for a cruise missile.
