In a message on Sunday, Putin congratulated his Iranian counterpart Masoud Pezeshkian on Nowruz.
In his greeting message, Putin wished that the people of Iran pass through these difficult tests with dignity.
Putin also stressed that Russia will remain a loyal friend and a reliable partner for Iran during this challenging time.
The US and the Israeli regime launched a large-scale unprovoked military campaign against Iran following the assassination of Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei, along with several senior military commanders and civilians on February 28.
The attacks have involved extensive aerial strikes on both military and civilian locations across Iran, causing significant casualties and widespread damage to infrastructure.
In response, the Iranian Armed Forces have carried out retaliatory operations, targeting American and Israeli positions in the occupied territories and at regional bases with waves of missiles and drones.
