Israeli forces are carrying out more special operations beyond the country's borders and will be ready to attack Iran's nuclear sites if ordered, the chief-of-staff said in an interview on Sunday.

In an extract from an interview with the top-selling Yediot Aharanot daily, Lieutenant General Benny Gantz said that 2012 would be a critical year in efforts to halt what Israel and much of the international community believe is an Iranian nuclear arms programme.

"We think that a nuclear Iran is a very bad thing, which the world needs to stop and which Israel needs to stop -- and we are planning accordingly," Gantz said.

"In principle, we are ready to act.

"That does not mean that I will now order (air force chief) Ido (Nehushtan) to strike Iran," he added in the interview which will be published in full on Wednesday, on the eve of Israel's 64th anniversary as a state.

The United States says it does not believe Iran has so far taken a decision to develop a nuclear weapon, or that the time is right for military action, preferring to give international sanctions time to work.

But Israel, which sees a nuclear Iran as a threat to its very existence, claims Tehran may be on the cusp of "breakout" capability -- when it could quickly build a nuclear weapon -- and it does not rule out staging a pre-emptive strike of its own.

Gantz said he had increased the number of Israeli special operations in other countries but did not give details.

"I do not think you will find a point in time where there is not something happening, somewhere in the world," he said. "The threat level is also higher."

"I'm not taking the credit," he added. "I'm just accelerating all those special operations."

Iraq PM meets Ahmadinejad at start of visit
Tehran (AFP) April 22, 2012 - Iraqi Prime Minister Nuri al-Maliki met Iranian President Mahmoud Ahmadinejad on Sunday at the start of a two-day visit to boost relations between their Muslim states.

"If Tehran and Baghdad are strong, the region will have no place for the United States and the Zionist regime," Ahmadinejad said, quoted by state news agency IRNA, in reference to Tehran's arch-foe Israel.

He said there was "no limit to the strengthening of political, economic and cultural ties" between them.

Such moves would serve to "boost stability and security in the region," chimed in Maliki, who also held talks with parliament speaker Ali Larijani.

The visit notably comes ahead of a May 23 meeting to be hosted in Baghdad between Iran and the P5+1 group of world powers on Tehran's disputed nuclear programme.

The mission underlines the current good ties between the two Shiite-dominated administrations -- a far cry from the war in the 1980s when Baghdad was run by Saddam Hussein and his Sunni-led government.

Maliki, who was at the head of a delegation of ranking Iraqi political and economic officials, was also to see Iran's chief nuclear negotiator Saeed Jalili, and to attend a meeting of the Iran-Iraq joint economic commission.

It was Maliki's first visit to Tehran since October 2010, when he was trying to secure regional backing for a second term as premier following inconclusive March parliamentary polls.

Iraq and Iran have similar positions on the crisis in Syria, where the regime of Iranian ally President Bashar al-Assad has been carrying out a bloody crackdown on an uprising against his rule, in which thousands have died.

But there are some contentious issues between the two countries, including the diversion by Iran of rivers that flow into Iraq, as well as borders and oil.
