Iran says it's willing to enter another round of talks with the US over Iraq security. Iran and the US have held three rounds of ambassador-level talks on Iraqi security in Baghdad since last May. 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 Teheran have no formal relations. Hosseini did not a give possible time for the next round of talks.
