Two brothers arrested in Saudi Arabia had transported the explosives used in the suicide bombing of a Shiite mosque in Kuwait, the interior ministry said Tuesday. It said Majed al-Zahrani and Mohammad al-Zahrani smuggled in the explosives in an icebox by car through Nuwaiseeb border post from Saudi Arabia, a day before the June 26 bombing that killed 26 people. The two Saudis then delivered the explosives near the border post to Abdulrahman Sabah Eidan Saud, a stateless Arab who passed them on to the suicide bomber and drove him to the target mosque, the ministry said.
