Accused kidnappers are rogue Hamas branch
On June 26, the Shin Bet allowed the release of the names of the two men suspected of orchestrating the kidnapping of the three yeshiva (religious high school) students in the Etzion settlement bloc. The suspects are Marwan Qawasmeh and Amar Abu Aisha.
According to Palestinian sources, Palestinian security forces had already reported to Israel that these two suspects had disappeared from Hebron within 24 hours of the abduction. That was the first clue in the investigation and the reason why Israel pointed an accusatory finger at the Hamas infrastructure in Hebron. But while Israel continues to accuse the Hamas movement and its leadership of being responsible for the abduction, Palestinian security forces attribute the abduction to the Qawasmeh clan of Hebron specifically. Though the clan is known for identifying with Hamas, it also has a well-earned reputation as troublemakers. Not only does it tend to ignore the movement's leaders. It even acts counter to the policies being advocated by the movement.
That is why officials in the Palestinian Authority (PA) were shocked by the timing of the three boys'abduction, just two weeks after the establishment of a Palestinian unity government. After all, the very creation of this new coalition came with the assumption that the Hamas leadership had come to terms with reality and moderated their positions.
Enter the Qawasmeh clan. The total number of people belonging to the clan is estimated at about 10,000, making it one of the three largest clans in the Mount Hebron region. At least 15 members of the family were killed during the second intifada, nine of them while committing suicide attacks against Israel. All of the terrorists lived in the Abu Qatila neighborhood, within a radius of less than 1 kilometer (0.6 mile) from one another. Whenever the head of the terrorist organization within the clan was assassinated or arrested by Israel, one of his brothers or cousins was selected to replace him.
For instance, when the head of the group, Abdullah Qawasmeh, was assassinated during the second intifada, he was succeeded by his cousin Basel Qawasmeh. When Basel was assassinated by Israel, the person selected to succeed him was Imad Qawasmeh, who was apprehended by the Israel Defense Forces (IDF) in October 2003.
Marwan Qawasmeh, the man behind the abduction, emerged as a dominant figure in the clan after Israel arrested Imad Qawasmeh and sentenced him to life in prison.
Each time Hamas had reached an understanding with Israel about a cease-fire or tahadiyeh (period of calm), at least one member of the family has been responsible for planning or initiating a suicide attack, and any understandings with Israel, achieved after considerable effort, were suddenly laid waste. If there is a single family throughout the PA territories whose actions can be blamed for Israel's assassination of the political leadership of Hamas, it is the Qawasmeh family of Hebron.
If true, that clan surely seem to be troublemakers.
