THREE Russian FSB officers have been killed after their food delivery was reportedly spiked with arsenic and rat poison.

Officials claimed the alleged poisoning was the work of Ukraine’s underground “resistance forces” in Melitopol.

A fourth security service operative is reportedly in intensive care. 

There has been no confirmation from Russian officials about the alleged assassination of the FSB agents – once headed by dictator Putin.

Telegram channel Kremlevskaya Tabakerka reported: “The restaurant where the food and alcohol were delivered was searched, and no traces of poisons were found. 

“At the same time, the courier who delivered the food and alcohol disappeared without a trace.”

The poisoning claim was reported in Ukraine by the Kyiv Post, and apparently confirmed by exiled mayor Ivan Fedorov. 

Speaking on Ukrainian TV channel United News, Fedorov said: “They ordered food from a local cafe and after they were able to consume this food, they all got poisoned and some of them even died.

“They will definitely not be able to fight against our state anymore.

“It is interesting that they cannot find the courier who delivered the food, but this is the active resistance that continues in Melitopol after almost two years of occupation.”

The mayor said: “The elimination of the enemy is carried out not only by explosions, missile strikes, but also by resistance forces.

“For example, the other day there was another batch of eliminated enemies, namely poisoned enemies, which was even reported by enemy Telegram channels.”

The Telegram channel claimed two of the three dead FSB operatives had launched an investigation into an alleged grave of Russian Black Sea Fleet sailors recently found in Melitopol.

Seventeen mutilated bodies showing evidence of missile attack had been discovered, it alleged. 

Occupying forces have been repeatedly warned about the risk of food poisoning. 

Last month, cake and booze laced with deadly poison was allegedly delivered to a Russian military bash in a Ukrainian plot to assassinate dozens of top pilots.

The Bond-style plan to take out Putin’s top-brass cronies at the elite military academy was reportedly thwarted at the last minute.

But 77 guests avoided the killer treats as a pro-war Telegram channel reported “everyone is alive” following the alleged plot.

Russian pilots were marking the 20th anniversary of their graduation from the Armavir Higher Military Aviation School.

The guests included many highly decorated and senior ranking pilots from the Class of 2003. 

While the deadly 20 kilogram cake was cut, it was apparently left untouched as a crucial clue foiled Ukraine’s alleged plot at the last second.

And last year, two Russian soldiers died after eating poisonous pies given to them by Ukrainian citizens, Ukrainian intelligence claimed.

The soldiers, from the third Motor Rifle Division, are said to have died instantly after being given the delicacies as “gifts” by locals in Izium.

Another 28 Russians were said to have been rushed to intensive care after the poisoning, with hundreds of others suffering “severe illness” from poisoned food and drink.
