German Chancellor Angela Merkel on Wednesday called on the international community to remain unified in trying to persuade Iran to stop its nuclear program, but reiterated that she saw no military solution. Speaking before parliament, Merkel said Tehran's response was "not satisfactory." "We will not close the door to further negotiations, but as the international community, we cannot passively allow Iran to violate the rules of the IAEA," she said. "It is especially important to maintain the unity of the international community of states," she said. "There is no military option in Iran _ therefore this is about determination, but doing nothing cannot be the answer."
