The Israeli Air Force struck and killed Mahdi Vafaei, head of the Quds Force's Lebanon Corps Engineering Branch, in a targeted strike in the Mahallat area of Iran overnight, the IDF announced on Wednesday morning.

Vafaei was a key figure in the establishment of the underground terrorist infrastructure sites for Hezbollah and the Assad regime in Syria, and managed dozens of underground weapons storage projects in Lebanon.

The IDF also struck a factory that transferred chemical substances used in the Iranian regime’s development of chemical weapons on Tuesday, the IDF announced. 

The factory was owned by the Tofiq Daru Company, a principal supplier of fentanyl for the Organization of Defense Innovation and Research (SPND), Iran’s Defense Ministry’s development agency.

SPND is responsible for developing chemical weapons for the Iranian regime, said the military’s statements.

The strike comes amidst an IDF announcement that 100% of essential targets will have been destroyed by Wednesday as Israel doubles down on its strikes on sites deemed threatening to Israel. 

Among the recent targets are a weapon manufacturing site in Tehran and a uranium enrichment facility in Ardakan. 

Substances used for development of chemical weapons

According to the IDF, Tofiq’s factory disguised itself as a civilian company, but was used by the regime for the production of substances utilized in the research and development of chemical weapons.

“The Tofiq Daru Company knowingly and systematically supplied this deadly substance [fentanyl] to the SPND organization, which used it to conduct research and development of chemical weapons,” said the IDF.

Fentanyl is an anesthetic that is considered a highly lethal substance when used in high doses.

The military claimed that the strike on the factory “ impaired the Iranian terror regime's chemical weapons production capabilities.”

Additionally, the IDF assured that precautionary measures were taken to minimize possible harm to civilians.
