Iran says it will not hold a new round of talks with the US on security in Iraq until American forces end their current assault against Shiite militias. Iranian Foreign Ministry spokesman Mohammad Ali Hosseini's announcement Monday is the first official confirmation that the talks will be suspended. Iran's semi-official Fars news agency quoted an unnamed senior Iranian negotiator Saturday as saying new talks were not possible with continued US attacks against the Iraqi people. US and Iraqi forces have been battling supporters of radical Shiite cleric Muqtada al-Sadr. Washington has accused Iran of supporting Shiite militias in Iraq, a charge denied by Teheran.
