M. Star: terrorist scenario in doubt: So it goes
If it were a suicide bomber, the explosive device would have pierced the hull or at least caused visible damage from shrapnel. The terrorist theory is the favoured scenario because the United Arab Emirates state news agency quoted an unnamed coast guard official as saying they found the remnants of handmade explosives on the hull and that terrorists were to blame. The Japanese government, meanwhile, is still carrying out its investigations into the cause of the blast on board the M Star, a government official said. The Straits are far outside of the operational radius that one would expect for a group that was operating in the Sinai to be able to then launch an attack in the Persian Gulf - that's showing quite a transnational operational reach. The damage to the M Star's hull was probably caused by a collision?
