"Eighteen Palestinian citizens have been killed in recent hours due to improper airdrops of humanitarian aid from airplanes," the Gaza media office said in a statement.
Twelve starving Gaza residents drowned in the sea while attempting to get the parcels containing humanitarian aid and another six died in stampedes seeking to reach the boxes dropped from airplanes, the statement added.
"We hold the US Administration and the Israeli occupation responsible for the policy of famine and siege," the statement read.
It is not the first time the enclave's authorities have been criticizing the practice of aid airdrops. On March 8, the parachute of an air cargo did not work, and the container fell on the roof of a residential building, killing five people.
