Senior German diplomat visits Tehran for nuclear deal talks despite mounting US pressure

Tensions have soared in the Mideast recently as the White House earlier this month sent an aircraft carrier and B-52 bombers to the region over a still-unexplained threat it perceived from Iran.

In Berlin, the Foreign Ministry said Political Director Jens Ploetner was to hold talks with Iran's Deputy Foreign Minister Abbas Araghchi on Thursday to try salvage the nuclear deal signed in 2015 in Vienna. The accord has steadily unraveled since the Trump administration pulled America out of the deal, re-imposed and escalated US sanctions on Tehran last year.

The German envoy's visit also follows Iran's declaration earlier this month that the remaining signatories to the deal — Germany, France, Britain, China and Russia — have two months to develop a plan to shield Iran from American sanctions.

"The situation in the Persian Gulf and the region, and the situation surrounding the Vienna nuclear agreement, is extremely serious," the German Foreign Ministry said in an e-mail to The Associated Press.

"There is a real risk of escalation — including due to misunderstandings or an incident. In this situation, dialogue is very important."

With Iran's 60-day deadline, the ministry said there is still a "window for diplomacy to persuade Iran to continue its full compliance" and said Germany remains in close contact with the other nations that have been struggling to keep the deal alive.

The accord, intended to keep Iran from obtaining a nuclear weapon, promised economic incentives in exchange for restrictions on Tehran's nuclear activities. Despite efforts so far by the others to keep the deal from collapsing, Iran's economy has been struggling and its currency has plummeted after the re-imposition of US sanctions.

Iran continued abiding by the stipulations of the deal, according to a February report by the International Atomic Energy Agency, though it expressed increasing frustration with the inability of the Europeans to provide economic relief. A new IAEA report is due out soon.

Then on Monday, Iran announced it had quadrupled its production capacity of low-enriched uranium. Iranian officials made a point to stress that the uranium would be enriched only to the 3.67 percent limit set under the nuclear deal, making it usable for a power plant but far below what's needed for an atomic weapon.

But by increasing production, Iran will likely soon exceed the stockpile limitations set by the nuclear accord, which would escalate the situation further.

Several incidents have added to the crisis, including the sabotage of the oil tankers off the coast of the United Arab Emirates, as well as a rocket that landed near the US Embassy in Baghdad. The US has blamed Iran for both incidents without publicly offering evidence. America also has evacuated nonessential diplomatic staff from Iraq amid the tensions.

Also, Iran-aligned rebels in Yemen have targeted a Saudi pipeline and sent a bomb-laden drone to target a Saudi airport with a military base on Tuesday.

The Pentagon was to present plans on Thursday to the White House to send up to 10,000 more American troops to the Middle East, to beef up defenses against potential Iranian threats, US officials said. Iran has watched warily as the USS Abraham Lincoln heads toward the Strait of Hormuz and B-52 bombers began flying missions in the region.

Iran's armed forces chief of staff, Gen. Mohammad Hossein Bagheri, said on Thursday the military will remain watchful about "deceptions by the US government and its adventurous" president.

"With the finger on the trigger, Iran is ready to respond to any invader strongly and with unbelievable speed," Bagheri said in a statement.

Iran's Foreign Minister Mohammad Javad Zarif was expected to arrive later on Thursday in Islamabad as Pakistan seeks to calm regional tensions. He was to hold talks with Pakistani officials on Friday.

"We believe the situation in the region is serious and needs to be addressed through dialogue by all parties," Pakistan's foreign ministry said in a statement. "We expect all sides to show restraint, as any miscalculated move, can transmute into a large-scale conflict."
