nvestigators have identified a suicide bomber in the weekend attacks that killed scores in this Red Sea resort, saying he was an Egyptian with Islamic militant ties, security officials said Tuesday as investigators questioned dozens more people. The bomber who was identified carried out the devastating truck bomb attack on the Ghazala Garden's hotel in Sharm el-Sheik. DNA tests identified him as Youssef Badran, an Egyptian Sinai resident with ties to Islamic militants, the officials said on condition of anonymity because the release of the details had not been authorized. Police held members of Badran's family for questioning and were trying to determine his associates, the officials said. Across Sinai, security forces took in 70 people for questioning on Tuesday, bringing to 140 the number held since the early Saturday blasts.
