A Palestinian from the Gaza Strip is being detained by Israel for "security crimes," a Be'er Sheva court revealed Wednesday.

The Be'er Sheva Magistrate's Court partially lifted a gag order on the case, revealing that Wael Abu Reda was detained three weeks ago by the Shin Bet security service and Israel Police on suspicion of "security crimes."

The court extended his remand by eight days. The remaining details of the case were kept under a gag order.

The story is reminiscent of the 2011 disappearance of Palestinian engineer Dirar Abu Sisi, who went missing while in the Ukraine. Israel later confirmed it was holding Abu Sisi, whom it accused of playing a central role in Hamas' missile and rocket development program.

Abu Sisi's family claimed he was kidnapped by the Mossad from a Ukrainian sleeper train by six men who apprehended him during an overnight journey. The UN refugee agency UNHCR echoed those accusations. An indictment that was eventually served against him did not mention the circumstances in which he made his way to Israel. Those details were put under a gag order.

The Shin Bet said in a statement following the indictment that Abu Sisi "divulged valuable information in his interrogation about Hamas' military wing, structure and decision-making processes."

The indictment and the Shin Bet statement portray Abu Sisi as a central Hamas leader.
