An explosion from a bomb hidden in a garbage bin wounded a passer-by in a Palestinian refugee camp near the southern port city of Sidon, Lebanese security officials said Friday. The officials say the attack occurred in the Ein el-Hilweh refugee camp near the home of Imad Kharoub, a supporter of Jund al-Sham, a group that follows the extremist ideology of al-Qaida. Kharoub was not hurt, the officials said on condition of anonymity because they were not authorized to speak to the media.
