TEHRAN (Reuters) - Supporters of Iran's defeated presidential candidate Mirhossein Mousavi prepared to heed his rallying call for a national day of mourning on Thursday for those killed in post-election clashes.

State media said seven people were killed in an opposition protest in Tehran against what Mousavi says was a rigged election last week in favour of hardline incumbent President Mahmoud Ahmadinejad.

On his website, Mousavi called on Iranians to stage peaceful demonstrations or gather in mosques on Thursday.

"In the course of the past days and as a consequence of illegal and violent encounters with (people protesting) against the outcome of the presidential election, a number of our countrymen were wounded or martyred," he said.

"I ask the people to express their solidarity with the families ... by coming together in mosques or taking part in peaceful demonstrations."

Official results from Friday's vote showed Ahmadinejad had won a landslide, leading to daily clashes between Mousavi backers, anti-riot police and Islamic militiamen. Authorities have dismissed opposition allegations of vote rigging.

Despite calls by Supreme Leader Ayatollah Ali Khamenei for national unity, Mousavi supporters have continued to pour on to the streets.
