Israeli secret service has acknowledged that a kidnapped Palestinian engineer has been kept in an Israeli jail for questioning.

Dirar Abu Sisi, 42, was whisked away in the early hours of February 19 after boarding a train bound for the Ukrainian capital, Kiev.

Israel’s Shin Bet internal security service confirmed on Sunday that it is holding Abu Sisi at Shikma prison in Ashkelon, a city 13 kilometers (8.1 miles) north of the border with the Gaza Strip, AFP reported.

Israel had earlier denied it had any information on the case.

Earlier in March, an Israeli court in Petah Tikva upheld a ban on publishing any information from Israel about the mysterious disappearance of Abu Sisi.

Abu Sisi was a manager at the Gaza Strip’s main power plant. Some reports have linked Abu Sisi’s abduction to Israel’s intent to sabotage the work of the only power generation unit in Gaza.

The abduction of Sisi has raised the concern of Palestinians, who are living in Ukraine, about insecurity and expansion of Mossad’s activities in the European country.

Hamas has also condemned the abduction and demanded the engineer’s release.

"This kidnapping violates international law and Ukraine’s sovereignty. It is further proof of the contempt of the Israeli occupation for the international community," spokesman Sami Abu Zohi said.
