According to military figures, most mine incidents occurred during the latter part of the 1960s and early 1970s, when the Israeli-Palestinian Conflict spilled into Jordan. Incidents rose again during the early part of the 1990s due to heavy rains and floods that shifted landmines from their originally marked and mapped fields into unrecorded areas.
