Heavy gunfire between Taliban militants and the Iranian military broke out at a shared border on Saturday, resulting in the deaths of at least two Iranian border guards and more wounded.

The flare-up between Taliban-controlled Afghanistan and the Islamic Republic of Iran comes amid a fierce dispute over water rights, specifically concerning access of drought-stricken Iran to the Helmand River.

Bank of Russia Governor Elvira Nabiullina visited Tehran for talks with her Iranian counterpart, Mohammad-Reza Farzin, Bloomberg reported on Thursday.

An Iranian official said on Tuesday that an attack on nuclear facilities would mean a widespread war that Israel would bear responsibility for. Speaking to the Qatari-based Al Jazeera network the official said Israeli threats would not change the course of things.

Iran successfully test-launched a ballistic missile with a potential 2,000-km range on Thursday, state media said, two days after the chief of Israel’s armed forces raised the prospect of “action” against Tehran over its nuclear program.

Iran, which has one of the biggest missile programs in the Middle East, says its weapons are capable of reaching the bases of arch-foes Israel and the United States in the region.

Whether Israel’s escalating threats of war with Iran over its nuclear program are saber-rattling or something more serious is a mystery even to the CIA, according to a portion of a top-secret intelligence report leaked on the platform Discord earlier this year. The uncertainty about the intentions of one of the U.S.’s closest allies calls into question the basis of the “ironclad” support for Israel publicly espoused by the Biden administration.

The US and UK should leave Iran alone, the head of Russia’s Foreign Intelligence Service (SVR), Sergey Naryshkin, has said. The official also suggested that the two nations are dismayed by the success of China’s efforts to reconcile Iran and Saudi Arabia.  

Speaking on Wednesday at the International Meeting of High Representatives for Security Issues, Naryshkin said he would advise the “Anglo-Saxons to take care of their own internal civil conflicts. Or better yet, go to their old pal – the devil.” 

The US Defense Department is sending its warships through the Strait of Hormuz at an increased pace. The operations are a reaction to rising tensions with Iran.

Last month, the US seized a tanker carrying Iranian oil to China. In response, Tehran took control over two commercial ships in the Persian Gulf. Washington was irate with the retaliatory seizures, with the commander of the US Navy’s Fifth Fleet, Vice Adm. Brad Cooper, declaring on Monday that “Iran’s actions are unacceptable.” 

Turkish intelligence (MIT) says it has uncovered a spy network linked to the Mossad, the Israeli intelligence agency, according to Turkish media reports on Tuesday. The network allegedly operated within Turkey and consisted of 15 individuals.

The investigation led to the arrest of 11 members, who reportedly were trained in Israel and sent to Turkey with the aim of establishing a company involved in trading with Iran.

Near a peak of the Zagros Mountains in central Iran, workers are building a nuclear facility so deep in the earth that it is likely beyond the range of a last-ditch US weapon designed to destroy such sites, according to experts and satellite imagery analyzed by The Associated Press.

The photos and videos from Planet Labs PBC show Iran has been digging tunnels in the mountain near the Natanz nuclear site, which has come under repeated sabotage attacks amid Tehran’s standoff with the West over its atomic program.

Five Iranian border guards were killed in a clash with an unknown armed group trying to enter the country near the Pakistani border, state TV reported Sunday.
