Official Palestinian Authority security organs have issued a call for their terrorist-operatives in the field to cease all violence, saying that a ceasefire now is in the \"Palestinian national interest.\" However, Israeli security sources feel that the call will fall on deaf ears, following yesterday\'s announcement by the G-8 countries in favor of agreed-upon international observers. The Israelis feel that the G-8\'s call merely \"whetted\" the Palestinians\' appetite for more gains, and that they will resume intense violence when the G-8 conference adjourns.
