Saudi Arabia could start making investments in Iran "very quickly" after they agreed to restore diplomatic ties, the Saudi finance minister said on Wednesday, despite sweeping US sanctions against the Islamic republic.

Mohammed Al-Jadaan said there were "a lot of opportunities" in Iran and that he couldn't see any reason to prevent investments taking place between the two Gulf heavyweights.

The recent deadly earthquake in Turkey and Syria which caused billions of dollars in damage has boosted the prospects of Syria's once widely shunned president return to the Arab fold, but appears unlikely to jump-start large-scale reconstruction in the war-ravaged country.

As Syria's conflict enters its 13th year Wednesday, President Bashar Assad's government still refuses to make concessions to his domestic opponents, rejecting long-standing demands by the United States and its allies as a political solution remains elusive.

Twenty years after the U.S. invaded Iraq — in blinding explosions of shock and awe — American forces remain in the country in what has become a small but consistent presence to ensure an ongoing relationship with a key military and diplomatic partner in the Middle East.

The roughly 2,500 U.S. troops are scattered around the country, largely in military installations in Baghdad and in the north. And while it is a far cry from the more than 170,000 U.S. forces in Iraq at the peak of the war in 2007, U.S. officials say the limited — but continued — troop level is critical as a show of commitment to the region and a hedge against Iranian influence and weapons trafficking.

Russian President Vladimir Putin on Wednesday hosted Syrian leader Bashar Assad in the Kremlin for talks expected to focus on rebuilding Syria after a devastating civil war and mending Damascus' ties with Turkey.

Welcoming Assad at the start of the meeting that comes on the anniversary of Syria's 12-year uprising-turned-civil war, Putin emphasized the Russian military's "decisive contribution" to stabilizing the country.

Hundreds of Israeli writers, artists and intellectuals on Tuesday called on Germany and Britain to cancel upcoming visits by Prime Minister Benjamin Netanyahu, saying his plan to overhaul Israel's judicial system has put the country on a destructive course.

Netanyahu's coalition, a collection of ultranationalist and ultra-Orthodox parties, has barreled ahead with legislation that aims to weaken Israel's Supreme Court and give them control over the appointment of the nation's judges.

A former top Jordanian official imprisoned in an alleged plot against the Western-allied monarchy was rushed to the hospital over the weekend after a three-week hunger strike, the man's American lawyer said.

Bassem Awadallah, who is a dual Jordanian-American citizen, was suffering from low blood pressure and sugar levels when he was hospitalized Saturday, his representatives said.

Israel's parliament on Tuesday advanced a bill that would let lawmakers pass laws that the Supreme Court cannot overturn — a key piece of legislation in Benjamin Netanyahu and his allies' proposed judicial overhaul that has divided the country.

Netanyahu's governing coalition of ultranationalist and ultra-Orthodox parties has pressed ahead with its legislative blitz despite calls for compromise and demonstrations that have drawn tens of thousands of Israelis to the streets over the past two months.

Even as they highlight the historic nature of a shock rapprochement between Saudi Arabia and Iran, regional officials and analysts are injecting a note of caution into their assessments of what it all means.

The deal announced Friday, brokered by China, stands to end a seven-year rupture in diplomatic ties between the two heavyweights that has stoked unrest across the Middle East.

Israeli Prime Minister Benjamin Netanyahu's political allies pressed ahead Monday with their plan to overhaul the judiciary, advancing a bill that would protect the long-serving leader from calls that he be removed from office over his corruption charges.

The steps were the latest in a series of legislation seen by critics as concentrating power in the ruling coalition's hands. The government has pledged to plow ahead with the legal changes despite widespread opposition.

Iran said Monday it would welcome restoring ties with Bahrain to end seven years of ruptured relations, following a recent China-brokered deal to heal rifts between Tehran and Riyadh.

"The resumption of political relations between Iran and Saudi Arabia shows the effectiveness and success of the diplomatic solution to resolve misunderstandings," said Iran's foreign ministry spokesman Nasser Kanani.
