The Iranian president stressed that his country is seeking good relations with its neighbors, including Saudi Arabia.

Also, at a meeting with Iranian foreign minister, Mohammed Javad Zarif, Iraq's foreign minister, Ibrahim Jaafari offered to mediate in the row.

On Tuesday, Iran's President Hassan Rouhani said Riyadh can not hide the "crime" of killing a religious cleric by severing diplomatic ties with Tehran.

"Saudi Arabia is responsible for the damage to the embassy building and the injury to some of its staff", Iran's foreign-ministry spokesman, Hossein Jaber Ansari, reportedly said on the state television network, adding that the damage was "deliberate and intentional".

An Associated Press reporter in Yemen's capital says he sees no damage at the Iranian Embassy after the Islamic Republic said it was hit in an overnight Saudi-led strike.

"This move was unacceptable and wrong and we should learn a lesson so that, while preserving the right to protest, such an act should not happen", he added.

A group of Sunni Muslim countries have pledged their support and allegiance to the Arabic kingdom, Bahrain, Sudan, Djibouti, Turkey and Jordan by severing ties with Iran.

Authorities in Tehran on Thursday accused the Saudi-led coalition now intervening against Houthi rebels in Yemen of hitting the Iranian Embassy in Sanaa in an overnight airstrike. This came after fierce protests in Iran against the execution of top Shia cleric Nimr al-Nimr by Saudi Arabia.

Nearly 6,000 people have been killed since Saudi Arabia and a coalition of Sunni nation allies started airstrikes in Yemen in March 2015, almost half of them civilians.

Shia-dominated areas in eastern Saudi Arabia, the home of al-Nimr, held a three-day mourning period for the cleric.

He previously said that the souring of relations between Saudi and Iran puts Doha in a tricky position, given its "intimate" relationship with the kingdom and its business ties to Tehran.

The growing tensions have heaped doubt on a UN-backed plan that foresees talks between the Syrian sides this month in a bid to end a war that has claimed more than a quarter of a million lives.

"I have spoken to the foreign ministers of some of the Arab countries to reduce the consequences of this issue and prevent enemies from dragging the region into a war that can have no winners", Jaafari said.
