The US Central Command (CENTCOM) denied on Friday that a deadly aid airdrop which killed civilians in the Gaza Strip was conducted by US troops.

In a social media statement, CENTCOM said it was aware of reports that a humanitarian airdrop killed civilians.

"We express sympathies to the families of those who were killed. Contrary to some reports, this was not the result of US airdrops," the statement read.

Gaza's Hamas-controlled Health Ministry said that five people were killed and another 10 wounded on Friday by an airdrop in the north of the territory. 

The parachute for the food aid container failed to open properly, meaning the package fell to ground in freefall.

In recent weeks, various countries have begun dropping aid shipments via parachute into Gaza to address food shortages and other issues. Despite criticism from experts, who say land shipments would be more efficient and less dangerous, the practice has intensified since the US adopted it on Saturday.

Jordan also distanced itself from the incident. Unnamed sources told Jordan's state news agency on Friday that the technical error had not occurred on any of the Jordanian aircraft involved.
