Iran summoned Ukraine's charge d'affaires in Tehran on Monday over his country's comments on a drone strike on a military factory in the central Iranian province of Isfahan, according to the semi-official Tasnim news agency.
In Ukraine, which accuses Iran of supplying hundreds of drones to Russia to attack civilian targets in Ukrainian cities far from the front, a senior aide to President Volodymyr Zelenskiy linked the incident directly to the war there.
"Explosive night in Iran," Mykhailo Podolyak tweeted. "Did warn you."
Iran has acknowledged sending drones to Russia but says they were sent before Moscow's invasion of Ukraine last year.
Moscow denies its forces use Iranian drones in Ukraine, although many have been shot down and recovered there.
The Kremlin on Monday condemned the Iran strike and said it was analyzing what had happened.
"In any case, one can only condemn such actions against a sovereign state," Kremlin spokesman Dmitry Peskov told reporters.
A US official said on Sunday that Israel appeared to have been behind the overnight drone strike. Iran said it had intercepted the strike and that there were no casualties or serious damage.
