TEHRAN, Iran — Conservative Iranian politicians and newspapers have expressed opposition to the new Iraqi-American security agreement and urged Iraq's parliament to reject it. But that view was not unanimous. At least one prominent figure, a senior judicial official, has said Iraqi negotiators have done well.

The government of Iran still has no official reaction to the security agreement, which sets a 2011 deadline for all American combat forces to leave. Iraq's parliament will vote on the agreement next Monday.

"We have to wait," Hassan Ghashgavi, a Foreign Ministry spokesman, said Monday at a news conference here. "Please allow us to make our stance after it is finalized."

The most critical comment came from the speaker of Iran's parliament, Ali Larijani, who said that the United States "was seeking to turn Iraq into one of its states," IRNA, the official news agency, reported Tuesday.

Two leading conservative dailies, Kayhan and Jomhouri Islami, denounced the agreement in similar editorials, saying it was aimed at exploiting Iraq.

Jomhouri Islami argued that the agreement contained no guarantee that American forces would leave Iraq by the end of 2011. "Most of the articles of the pact are about minor issues but in a few articles, the agreement provides Americans with all their exploitative intentions," the editorial asserted.

Iraq's prime minister, Nouri Kamal al-Maliki, a Shiite who has sought to cultivate good relations with Iran's Shiite-led government, has defended the agreement and called it Iraq's best option. Shiite politicians in Iraq's parliament have said privately that Iran's initial opposition to the agreement had softened.

The most positive Iranian appraisal came from the leader of the judiciary, Ayatollah Mahmoud Hashemi Shahroudi, who was quoted by Iranian newspapers as saying, "The Iraqi government has acted well."

"We hope the result will be both to the benefit of Islam and the sovereignty of the country of Iraq," he was quoted as saying. "We hope that American troops leave Iraq according to the plan."
