Tehran/Hamburg, June 25 (DPA) Mehdi Karroubi, who came third in Iran’s disputed presidential elections, cancelled a ceremony planned for Thursday to mourn the deaths of those killed during the protests against alleged election fraud, his website said.

The moderate former speaker of parliament plans to hold the ceremony next week instead. Karroubi’s camp said the government refused to provide a location for the ceremony, as the interior ministry has banned all protest gatherings.

The government has clamped down hard on protests, insisting it would not budge over the disputed elections.

Karroubi earlier assailed the regime, saying he would not accept the election results and therefore also regarded the new government as not legitimate.

Opposition leader Mir-Hossein Moussavi called on protesters to keep rallying but to refrain from violence.
