The Bedouin Free Army, described by State Department officials as an unambitious offshoot of the PLO, is claiming responsibility for Sunday's overturning of a garbage can near the Western Wall. According to reports, the group intended to bring attention to what they called a 'serious lack of pens' in Bedouin Army encampments near the Gaza Strip. Israeli officials had ignored the group's most serious act prior to Sunday, the 1995 slamming down of a phone receiver 'really hard,' according to State Department files. No one was hurt in the trash can incident, though several pieces of crumpled paper, three falafel balls and a shoe were badly scattered.
