Efforts to fight terrorism are not enough on their own unless people contribute to investigations, Alavi said.
Iran has uncovered and disbanded 10 terrorist groups since mid-October, the Intelligence Ministry has said.
Intelligence Minister Mahmoud Alavi made the comments while addressing a group of scholars in the western province of Kurdistan Monday.
The Islamic Republic has “vigilantly” obstructed any move by terrorists using the country’s “intelligence dominance.”
He went on to hail the Iranian nation’s support for Iran’s intelligence community, noting that efforts to fight terrorism “are not enough on their own” unless people contribute to investigations.
Alavi made the remarks in the wake of the deadly Paris attacks that left 132 people dead and many more injured.
Following those attacks and earlier deadly bombings in Beirut, Alavi said Sunday that the recent incidents “are a serious alert to us too and should be subjected to expert attention.”
