OK I'll take up that challenge. Since it happens pretty much every day, and you seem to think it doesn't happen very often, then either you have a very high standard of what constitutes "often", or you're very wrong about the news adequately informing everyone.
Lets start with the past week:
The man killed Thursday morning by a Palestinian mortar shell attack has been identified as 51-year-old Amnon Rosenberg of Kibbutz Nirim. Rosenberg, a member of the kibbutz since 1982, is survived by a wife, Tali, and three children – Dor, Eldar and Yarden.

The rocket hit the Gaza side of the crossing, wounding a Palestinian worker there, Palestinian doctors said.
Government spokesman David Baker said Wednesday's attack showed terrorist groups' "total disregard for the well-being of the Palestinian people."
