"The government should answer to the demands of its people, be it Syria, Yemen or other countries," the ISNA news agency quoted him as saying.

"The people of these nations have legitimate demands and the governments should reply to these demands as soon as possible," Salehi added.

"We have the same stance towards popular developments in the Middle East and North Africa. We believe that the developments in the region emanate from discontent and dissatisfaction in these countries," he said.

But he warned against about toppling the Syrian regime.

"A vacuum in the Syrian regime would have an unpredictable impact for the region and its neighbours," Salehi said, referring to calls by the United States and European leaders for Assad to step down.

Washington, the European Union and Syrian opposition groups have accused Tehran of helping Syrian security forces put down the uprising, a claim vehemently denied by Iran.

Salehi's comments came two days after Iranian President Mahmoud Ahmadinejad called for dialogue between Damascus and the opposition to end months of deadly violence.

"The people and government of Syria must come together to reach an understanding," Ahmadinejad said on Wednesday.

Tehran has supported the protests in all Arab countries except Syria, its main Arab ally, where the Islamic republic backed the government of President Bashar al-Assad, asking him to implement some reforms.

At the same time, Iran has accused arch-foes Israel and the United States of trying to undermine Syria.

The protest in Syria, which began in mid-March, has left more than 2,200 people dead, according to the United Nations.

Salehi once again accused "foreigners" of interfering in the domestic affairs of the regional nations, including Syria.

"Syria is an important link in the resistance chain (against Israel) and some want to cut off this link in the chain," Salehi added.
