Iran protests: Your views
Thousands of opposition supporters have been protesting in Iran, with two people reportedly killed in violent clashes between the protesters and security forces on Monday.
Information has been difficult to gather from people on the ground in Iran, due to communication restrictions, but many have been using social media outlets to send video and updates.
Here is a selection of footage and comments from YouTube and Twitter users in the country:
Videos taken of protests
In this video the crowd chants "God is great" until tear gas is thrown, when the shouts change to "don't run, don't run". The footage was taken on Monday, 14 February.
The translation of the conversation heard in the video below, shot on Monday, is as follows:
First man: "Show this! It is written for news agencies."
Man filming: "Bring up so it will cover your face."
(Written on the white board: Khameni is a murderer! His religious authority is illegitimate!)
Man filming: "Where can I escape if they (Basijies) come for me?"
Another man: "Go home! Where do you live? My place is up there."
Man filming: "Choose a house for me that I can shelter in if they come for me. I was beaten a while ago."
In the video below, shot on Monday, people appear to be trying to lead away a soldier, who is then protected by others, as tear gas is fired in the background.
