Iran says it's willing to enter another round of talks with the US over Iraq security. Foreign Ministry spokesman Mohammad Ali Hosseini said Monday that Iran will "continue the talks with necessary conditions." He says the US sent an official request for talks through the Swiss Embassy in Tehran because Washington and Tehran have no formal relations. He did not a give possible time for the next round of talks. Washington accuses Iran of funneling arms to extremist groups in Iraq, but Tehran denies that.
