Iran said Sunday its nuclear talks with Europe were moving too slowly, adding that it didn't rule out negotiations with Washington as long as America recognizes Tehran's right to a peaceful nuclear program. Foreign Ministry spokesman Hamid Reza Asefi said a permanent halt of Iran's nuclear activities was out of the question but said it was not yet ready to declare the "complicated and difficult" talks with Europeans a failure. "Talks with Europe have not met our satisfaction yet," Asefi told reporters. "The talks are taking longer than we expected."
