"We wanted to leave behind the Gaza nightmares and move to Ukraine," the woman told Yedioth Ahronoth.
The 2000 weekly reported that on February 18, while traveling on a train from Kharkov to Kiev, the engineer was kidnapped by unknown assailants.
"My husband has no enemies, neither in Ukraine nor in Palestine. He is not a prominent businessman and not a wealthy man, so there was no reason to kidnap him for a ransom," the woman claims, blaming Israeli intelligence agents for his mysterious disappearance.
The stewards on the carriage the engineer was kidnapped from reported at first that he was taken by two men who presented documents saying they belonged to a certain secret services. The stewards later said they did not wish to testify and that Abu Seesi was not kidnapped.
The Palestinian interior ministry issued a statement on the engineer's disappearance on February 23. Dr. Ahmed Ziad Sharif, the man's relative, said he must have been kidnapped as no arrest warrant had been issued against him by the Ukrainian authorities.
A spokeswoman for Ukraine's security service told Yedioth Ahronoth that she had no information about the alleged kidnapping. A Ukrainian foreign ministry spokesman said he had heard about the incident, which is being investigated by the Ukrainian police.
