Syrian President Bashar Assad hailed the "resilience" of Iran in striking a landmark nuclear deal with world powers, according to his Facebook page on Wednesday.

"In a telephone call to President Hassan Rouhani of the Islamic Republic of Iran, President Assad reaffirmed the Iranian diplomatic success... leading to the deal with the P5+1 countries."

Iran's top diplomat said Wednesday that Tehran and Ankara would press for a ceasefire in Syria ahead of peace talks planned for January, the Mehr news agency reported.

"All our efforts should be carried out to finish the conflict and reach a ceasefire even before Geneva 2," Foreign Minister Mohammad Javad Zarif said after a meeting with his Turkish counterpart Ahmet Davutoglu.

The March 14 general-secretariat hoped on Wednesday that Iran's agreement with major powers would lead to the withdrawal of what it called Iran's elite Revolutionary Guards from Lebanon and Syria.

Following its weekly meeting, the general-secretariat welcomed the deal struck between Tehran and world powers, saying it comes in conformity with the conditions set by the international community and the International Atomic Energy Agency.

Iran, the main regional ally of the government in Damascus, said Tuesday it is ready to take part in a peace conference on Syria but will not accept any preconditions.

The conference, known as Geneva II and initiated by Russia and the United States, is scheduled to be held in the Swiss city on January 22 after a series of delays. Its participants are still undecided.

President Barack Obama on Monday defended his administration's approach to Iran, insisting that "tough talk" alone would not guarantee U.S. security.

"Huge challenges remain, but we cannot close the door on diplomacy, and we cannot rule out peaceful solutions to the world's problems," Obama said following the landmark agreement reached in Geneva over the weekend concerning Iran's nuclear program.

Jordan, which is seeking to develop civil atomic energy, welcomed on Monday a nuclear agreement between Iran and world powers, saying it was "a step in the right direction".

"Jordan, like the international community, is awaiting details about the comprehensive implementation of the agreement, which should reflect positively on regional security," Information Minister Mohammad Momani said in a statement carried by state-run Petra news agency.

The list of participants for a long-awaited Syria peace conference scheduled for January 22 has yet to be established, U.N. and Arab League mediator Lakhdar Brahimi said Monday.

Pressed on who might take part in the so-called Geneva II talks, announced Monday, Brahimi said: "We haven't established a list yet."

Hizbullah on Monday noted that “the nuclear deal between the Islamic Republic of Iran and the P5+1 world powers is an exemplary victory and outstanding global achievement which the Islamic republic has added to its record that is full of triumphs and accomplishments.”

In a press release, the party said Tehran's “active diplomacy managed to reach an agreement based on the firmness of the Iranian stance and principles regarding the issue of the peaceful nuclear program.”

Foreign Minister Mohammad Javad Zarif said on Monday Iran's historic deal with world powers preserves the structure of the country's nuclear drive, while insisting the international sanctions regime had crumbled.

"The structure of Iran's nuclear program was preserved in the Geneva talks," Zarif told a gathering of nuclear scientists in Tehran, a day after an agreement was clinched in the Swiss city between Iran and world powers over the Islamic republic's disputed nuclear program.

Israeli Prime Minister Benjamin Netanyahu said Monday he will send his national security adviser to Washington for talks on a pending agreement with Iran on its nuclear program.

"I spoke yesterday with President (Barack) Obama and we agreed that in the coming days an Israeli team led by National Security Adviser Yossi Cohen would leave for talks with the United States on the final deal with Iran," Netanyahu said in an address to the Israeli parliament.
