Russia and Ukraine traded drone attacks Wednesday, with Ukraine apparently destroying a critical Russian defense system while the Kremlin once again attacked Ukrainian grain storage depots, officials said.

A Russian S-400 surface-to-air defense missile complex was later destroyed in occupied Crimea, according to claims from the Defense Intelligence of Ukraine. The Defense Intelligence said in a statement that Russia has a “limited number” of arsenal and the loss is a “painful blow” to its air defense system.

The long-range S-400 missiles have the ability to strike enemy aircraft and are considered one of the best available systems. Their range is 250 miles, and they can have multiple targets, according to The Associated Press.

Meanwhile, Russia attacked Ukraine’s southern Odesa region in a three-hour drone attack, prompting a fire at grain facilities, Odesa Regional Military Administration Head Oleh Kiper said in a telegram post.

The attack destroyed 13,000 metric tons of grain, bringing the total grain losses this month to 270,000 metric tons, Ukrainian Minister Olekanser Kubrakov said on Facebook.

The attack follows a series of Russian strikes on grain facilities after Russia pulled out of the Black Sea Grain Initiative last month, which had kept supplies flowing out of the major breadbasket nation.

The move threatens Ukrainian grain exports that bolster the country’s economy and supply the global market. The AP reports that in less than a year under the deal, Ukraine shipped 32.9 million metric tons of food supplies, most of it out of Odesa.

“The world needs to understand that attacks on grain infrastructure are attacks on African and Asian countries that have already run out of food,” Kubrakov wrote in a statement.

Russian officials also claimed to take out Ukrainian drones in Moscow and the surrounding region, Moscow Mayor Sergey Sobyanin said. According to Sobyanin, one drone smashed into a building under construction in Moscow, which was hit twice by drones before.

The drone was electronically jammed, according to Russia’s Ministry of Defense, which said two other drones were shot down by air defense systems in the Mozhaisk and Khimi areas. It said Ukraine was to blame for the attack, though Kyiv officials neither confirmed nor denied being behind the drone attacks.

In addition, three people died in the Belgorod region of Russia on the Ukrainian border after repeated shelling of a sanatorium, according to a telegram post from Gov. Vyacheslav Gladkov. He said shelling occurred at the sanatorium in the village of Lavy, around 25 miles from the border, killing two refugees and a staff member.
