CAIRO — A bomb blast hit a public bus in the Egyptian capital Cairo on Thursday, wounding five people, the Interior Ministry said, in an attack that raised concerns that a wave of violence blamed on militants that has targeted security forces and military for months is increasingly turning to hit civilians. The blast came a day after the government declared its top political nemesis, the Muslim Brotherhood, a terrorist organization, accusing it of being behind the violence. In Thursday's attack, a homemade bomb planted in a main intersection went off as a public bus passed in the eastern Cairo district of Nasr City, Interior Ministry said in a statement. Authorities then found at least one more bomb attached to an advertisement billboard apparently intended to hit security forces who responded to the first, state TV reported. – AP
