Iran says it has arrested dozens on suspicion of "terrorist activities" during a recent wave of protests.
The official IRNA news agency on Wednesday carried a statement from the Intelligence Ministry saying security forces confiscated arms and explosives from "safe houses" kept by people arrested during the protest that swept the country in late December.
The demonstrations were fueled by anger at the lackluster economy and corruption. Some demonstrators called for the overthrow of the government.
Clashes broke out at some of the protests, and at least 21 people were killed. Iranian security forces arrested some 3,700 people.
Iran's Supreme Leader Ayatollah Ali Khamenei has accused the U.S., Israel and other foreign powers of inciting violence to try and overthrow the Iranian regime.
