Ukrainian President Volodymyr Zelenskiy has announced sanctions against hundreds of individuals and companies, including Syrian President Bashar al-Assad and Iranians associated with the production of Shahed drones.

Zelenskiy said on March 18 that most of the more than 400 individuals and companies designated for sanctions are Russian and are involved in the defense industry, but Iranian and Syrian individuals — “those who help terror” — are also among the newly blacklisted.

According to a decree issued by Zelenskiy, the sanctions against Assad are imposed for 10 years. The new sanctions also list Syrian Prime Minister Hussein Arnous and Foreign Minister Faisal Mekdad.

In addition, the commander of the Islamic Revolutionary Guards Corps’ drone force was placed on the sanctions list. Sanctions were also introduced against other Iranian citizens.

Ukraine severed diplomatic relations with Syria last year. Assad recently visited Moscow and declared his full support for Russian President Vladimir Putin, calling Russia’s war against Ukraine a struggle “with “old and new Nazis.”

Russia has backed the Syrian Army in its fight against rebel forces in northern Syria, and Assad has said the presence of Russian troops in Syria is legitimate as his government has requested Moscow’s support.

Zelenskiy’s sanctions decrees list 141 legal entities, including companies from Russia, Iran, and the United Arab Emirates.

Zelenskiy said the Ukrainian sanctions are part of the global pressure on Russia.

“We study in depth each of our sanctioning steps,” he said on Telegram. The sanctions are aimed at “all those who produce weapons for terror against Ukraine, who help Russia incite aggression, in particular by supplying Shahed drones, and who support Russia’s destruction of international law.”

Russia has used Iranian-made Shahed kamikaze drones to attack critical Ukrainian infrastructure, including electrical substations and water facilities.
