The United States has briefed European allies on the reasons for the killing of Iran general Qasem Soleimani, NATO Secretary General Jens Stoltenberg said today.

“The US provided a rationale behind the action against Soleimani,” Stoltenberg said at a news conference after a NATO meeting in Brussels. The alliance received briefings from the government and the Pentagon.

Stoltenberg wouldn’t share any details about the reason, but said NATO “values and appreciates the briefing.” 

During today's briefing, all allies also agreed “Iran must never acquire a nuclear weapon” and all countries called for restraint and de-escalation, Stoltenberg said. 

The Secretary General said allies also expressed “a strong support for the fight against ISIS and training missions in Iraq.” He confirmed NATO is suspending its operations in the country “for the time being,” due to security concerns. Stoltenberg said the “situation is in close review” and he’s in contact with Iraqi authorities.
