Fadi al-Batsh, an engineering lecturer gunned down in Malaysia last week, had at least 14 bullets inside him. He was reportedly involved in talks with North Korea on arms intended for Gaza, as The New York Times reported Thursday. Mr. Batsh’s family blamed Mossad, the Israeli spy agency. That claim has been confirmed by Middle Eastern intelligence officials, who said the killing was part of a broader operation ordered by the Mossad chief, Yossi Cohen, to dismantle a Hamas project that sends Gaza’s most promising scientists and engineers overseas to gather know-how and weaponry to fight Israel. Israeli government dismissed suggestions that Israel’s Mossad spy agency assassinated him.
