Iranian lawmakers will have the chance to give their opinions on the nuclear deal with major world powers at around the end of September, parliament speaker Ali Larijani said Saturday.

Larijani did not, however, say whether parliament would be given a vote on the agreement, which provides for lifting sanctions on Iran in exchange for rolling back Tehran's nuclear program.

U.S. President Barack Obama welcomed Saudi Arabia's King Salman for a first and long-delayed White House summit Friday, marked by warm public words amid clashing views on Middle Eastern crises.

Obama made the rare move of greeting the 79-year-old monarch at the doors of the White House, as he hailed the "longstanding friendship" between the two countries.

U.S. Defense Secretary Ashton Carter offered assurances Friday that the Iran nuclear deal will leave Washington with a "more effective" military option if that becomes necessary.

Carter defended the agreement in an opinion piece in USA Today, arguing it would lead to a more durable outcome.

Iran's parliament speaker on Thursday said he expected a raucous debate in the Iranian legislature over approval of the nuclear deal which he said could unleash more drama than in the U.S. Congress.

Ali Larijani, who backs the agreement reached with the West, declined to say whether he believed lawmakers in the majlis would, in the end, support the deal.

Iran's embassy objected Thursday to being linked to a group set to go on trial in Kuwait on charges of plotting attacks on the Gulf Arab emirate.

In a statement published by Iranian state news agency IRNA, it also expressed "deep sorrow" at what it called a "systematic" Kuwait media campaign against relations between the two countries.

Israeli Prime Minister Benjamin Netanyahu defended Thursday his high-profile campaign to defeat the Iran nuclear deal after President Barack Obama secured enough backing to keep Congress from blocking it.

Netanyahu has repeatedly spoken out strongly against the agreement between Iran and six major powers aimed at rolling back the Islamic republic's nuclear program, even appearing before Congress in March.

Iranian supreme leader Ayatollah Ali Khamenei warned anew Thursday that there could be no nuclear deal with the West if sanctions imposed on Tehran are not lifted.

Khamenei, who has the last say in matters of policy, also said he believes Iran's parliament (majlis) should make up its own mind about landmark July 14 deal struck with six world powers.

More than 13 million children are being denied an education by Middle East conflicts, the U.N. said Thursday, warning "the hopes of a generation" would be dashed if they cannot return to classrooms.

In a report on the impact of conflict on education in six countries and territories across the region, the United Nation's children fund UNICEF said more than 8,850 schools were no longer usable due to violence.

Students from Iran's Islamic Bassij militia on Wednesday set fire to American, British and Israeli flags outside the former U.S. embassy in Tehran, AFP journalists said.

Some 30 people took part in trampling and burning the flags at a ceremony to unveil a plaque on the embassy's fence of 100 derogative expressions to describe the United States.

Saudi Arabia's top cleric hit out at Iranian film "Muhammad" on Wednesday describing its portrayal of the prophet's childhood as a "hostile act" and a "distortion" of Islam.

Iran's most expensive movie, which opened nationwide in the Shiite Islamic republic last week, depicts the prophet on screen, an act that is prohibited in Sunni Islam.
