While Germany and Britain have condemned Iranian missile strikes in Iraq, China only expressed its concern about tensions in the Middle East, but Russia even warned of a nuclear war.

The world powers late on Tuesday and early Wednesday, Jan. 8 showed their reactions after Iran fired “more than a dozen ballistic missiles” at two Iraqi military bases housing U.S. troops and coalition forces.

Iranian state television said the attack was in revenge for the U.S. killing of Gen. Qassem Soleimani, which the United States has designated as the head of the terrorist group Quds Force.

Germany criticized the Iranian strike, though none of the German troops in Iraq were injured.

Defense Minister Annegret Kramp-Karrenbauer told German public broadcaster ARD on Wednesday that the government “rejects this aggression in the sharpest possible terms.”

“It’s now particularly up to the Iranians not to engage in further escalation,” she said.

Britain, another European power, also condemned Iran for its strike at coalition forces in Iraq. The British Ministry of Defense said there were no British casualties in the attack, but Foreign Secretary Dominic Raab still urged Iran “not to repeat these reckless and dangerous attacks, and instead to pursue an urgent de-escalation.″

Raab said a war in the Middle East would only benefit ISIS and other terrorist groups.

From China, Foreign Ministry spokesman Geng Shuang said Wednesday that Beijing expressed concern about the tensions in the Middle East and hoped the matters could swiftly “cool off.”

Geng said China called for restraint on all sides, but accused the United States of abusing the rights of people in the region through its military actions.

From Russia, lawmaker Vladimir Dzhabarov warned that a conflict between the United States and Iran might even lead to a nuclear war.

“Reciprocal strikes by the U.S. and Iran may lead to an all-out war in the region. If Washington sees that it can’t achieve its goals, there’s a danger of a nuclear war,” Dzhabarov said, adding the U.N. Security Council should prevent further escalation in the Middle East.

From Japan, chief Cabinet spokesman Yoshihide Suga said it will urge all related nations to do their utmost diplomatic effort to help ease tensions following the Iranian missile strike.

In the neighborhood, United Arab Emirates Energy Minister Suhail Al-Mazrouei said, “The situation is not currently a war situation,” and that United Arab Emirates is “hoping for de-escalation.”
