TEHRAN, June 3 (Xinhua) -- A senior Iranian military official on Sunday ruled out the possibility of withdrawal of Iranian military advisors from Syria, Tasnim news agency reported.

"Iran and Syria enjoy deep relations that would not be influenced by the propaganda measures of anyone," Brigadier General Massoud Jazayeri told Tasnim on Sunday.

Iranians, unlike the U.S. military forces, have gone to Syria at the request of the Damascus government, Jazayeri said, stressing "the biggest fear of Israel is the presence of Muslim fighters in its proximity."

The United States and Israel are making "desperate efforts to change the situation," he added.

On Sunday, Israeli Prime Minister Benjamin Netanyahu said that Israel might launch more attacks against Iran to prevent it from establishing a presence in Syria.

"I will also insist on a basic principle: Israel retains, and will continue to retain freedom of action against the establishment of an Iranian military presence anywhere in Syria," Netanyahu said.

The second thing is the blocking of Iran's plans for expansion and aggression throughout the Middle East, he added.

Israel has reportedly carried out a series of deadly airstrikes in Syria, targeting mainly the positions of Iran and Hezbollah, a Lebanese Shiite militia, which fight alongside the forces of Syrian President Bashar al-Assad.

In the meantime, Secretary of Iran's Supreme National Security Council, Ali Shamkhani, said Sunday that recent allegations about negotiations between Iran and Israel over the former's role in Syria are totally "baseless," Press TV reported.

"The start and spread of such baseless rumors, which are increasing in number, represent a futile effort to give legitimacy to the Zionist regime (of Israel) and weaken the resistance front's will in its confrontation with Israel," Shamkhani was quoted as saying.
