Russian President Vladimir Putin and Chinese President Xi Jinping held a call on Thursday during which they both condemned Israel for striking Iran, the Kremlin said.

The two allies condemned “Israeli actions which violated the U.N. Charter and other norms of international law,” Putin aide Yuri Ushakov said, Reuters reports.

Xi called for an immediate ceasefire and warned the conflict between Israel and Iran risks spreading to other countries in the region.

“If the conflict escalates further, not only will the conflicting parties suffer greater losses, but regional countries will also suffer greatly,” Xi said during the call, according to the official Xinhua News Agency.

“The parties to the conflict, especially Israel, should cease fire as soon as possible to prevent the situation from escalating in turn and resolutely avoid the spillover of war,” he added.
