In capital Tehran, people gathered in Imam Hossein (AS) Square to show their support for the Islamic Republic.
Holding handwritten signs and placards, they condemned the continuation of hostilities by the United States and the Zionist regime against the Iranian nation.
They chanted "Down with US" and "Down with Israel".
The demonstrators reiterated their support for all Muslims and freedom-seekers worldwide and expressed their solidarity with the oppressed people of Palestine and the resistance front until the ultimate victory.
On December 30, 2009, millions of Iranians held nationwide rallies to condemn the foreign-orchestrated unrest which had erupted following the presidential elections earlier that year.
