Israel has denied access to Gaza for about one-third of all aid missions since the start of this month in a move that perpetuates “a continued cycle of deprivation and distress” for the population of the war-torn Palestinian territory, the UN has said.

The latest situation report from the UN Office for the Coordination of Humanitarian Affairs (OCHA) also reports that 198 people were killed and 430 injured in Israeli attacks between Friday and Monday.

Between August 1 and 11, Israeli authorities denied access to northern Gaza for 32 of 85 coordinated humanitarian aid missions. A further 13 were impeded by Israeli authorities and six were cancelled due to logistical and security reasons, the OCHA reports.

Out of 122 aid missions coordinated with Israeli authorities to southern Gaza, 36 were denied, eight were impeded and 15 were cancelled.

The blocking of aid missions “undermine[s] efforts to address urgent humanitarian needs”, the UN said.
