Dirar Abu Seesi or Abu Sisi (; born in 1969 in Jordan) is a Palestinian engineer. Abu Seesi was a deputy engineer for the Gaza Strip's sole electrical plant, which provides 25% of Gaza's power. According to Israel, he was also a weapons engineer for the Palestinian Hamas organization. In February 2011, he traveled to Ukraine, his wife's native country, to apply for citizenship, after coming to believe that Gaza was no longer a safe place to raise his six children. He disappeared in Poltava on February 19, and later turned up in an Israeli prison after being kidnapped by Mossad Israeli intelligence personnel. On April 4, 2011 he was indicted for his work for Hamas and was convicted on March 30, 2015 in a plea bargain. He is known by Israeli security services as the "father of the rockets". Abduction On the evening of February 18, after formally filing the papers for citizenship, Abu Seesi was traveling by train to the Kyiv airport for a reunion with his brother Yussef, who was residing in the Netherlands and whom he had not seen in 15 years. Just outside the city of Poltava, two men, who the family believes were Ukrainian security agents, entered the train and removed Dirar. After that, he disappeared. His wife Veronika, who was in Ukraine at the time as well, did not hear from him for a week. During that period of silence, she summoned the Ukrainian press and made allegations that the Mossad had kidnapped him. On February 27, the Palestinian Interior Ministry demanded that the Ukrainian Interior Ministry disclose the reasons for his disappearance. Dalia Kerstein, executive director of the Israeli human rights NGO, HaMoked, confirmed that the Gazan engineer was in an Israeli prison. Kerstein identified Abu Seesi's Israeli attorney Michal Orkabi, who confirmed that she represented him, but she could provide no further information due to a security gag order imposed by the Petah Tikva Magistrates' Court preventing her from speaking about the case. On March 20, the gag order was partially lifted with Israel admitting it was holding Abu Seesi. The United Nations High Commission for Refugees became involved in the case when it determined that Abu Seesi was classified as a refugee. An Associated Press article revealed that the UNHCR's Ukrainian representative asked Ukraine to account for any role its own officials may have played in the disappearance. Veronika Abu
