From CTV.ca:

A Canadian journalist has been detained in Iran, as authorities extended their crackdown on those protesting last week's disputed election to include those covering the demonstrations.

Newsweek magazine said in a statement its correspondent Maziar Bahari, a Canadian citizen, was detained Sunday morning and has not been heard from since.

The magazine defended its coverage as "fair and nuanced" and is calling for his release. More than 20 journalists have been detained in Iran over the last week.

The Canadian Department of Foreign Affairs says the Canadian embassy in Tehran will be demanding immediate consular access to Bahari.

Bahari came to Canada from Iran in 1988 as a political refugee. He has made a number of documentary films, several of them about Iran.

Iranian state television has raised the death toll from anti-government demonstrations to at least 17 and reported Sunday that the daughter of former president Hashemi Rafsanjani, along with four other family members, has been arrested for participating in the protests.
