Claims of more protests in Iran have dropped overnight after a week of unrest that killed at least 21 people.

It wasn't immediately clear if the drop on Thursday meant that the demonstrations are subsiding or that the Iranian government's blocking of social media apps has stopped protesters from offering new images of rallies.

In Tehran, streets were calm and clear at the start of the Iranian weekend.

On Wednesday, Iranian state media covered massive pro-government rallies in dozens of cities across the Islamic Republic.

The protests began on Dec. 28, sparked by Iran's flagging economy and a rise in food prices, before morphing over the following days into calls for the downfall of Iran's theocratic government.

Hundreds have been arrested by authorities over the unrest.
