Spanish Prime Minister Pedro Sánchez on Wednesday criticized the response of Israeli Prime Minister Benjamin Netanyahu to a targeted Israeli airstrike that resulted in the deaths of aid workers as "insufficient" and "unacceptable."

"We are waiting for a much more detailed clarification of what the causes have been, bearing in mind that the Israeli government knew about the actions and the itinerary of this NGO on the ground in Gaza," Sanchez said at a Doha conference. 

When asked to comment about Netanyahu's statements over the tragedy, he said: "It seems to me absolutely unacceptable, insufficient."

The recent attack on foreign aid workers occurred on April 1 and involved the targeting of seven aid workers from the US-based charity organization World Central Kitchen (WCK).

They were killed inside their vehicle by an Israeli airstrike despite being in a deconflicted zone and there being coordinated movement with the Israeli army. 

"Israel" claimed they were killed in error despite bombing them three consecutive times. 

In a deeply disturbing video posted on Netanyahu's Twitter account, the Prime Minister is observed grinning as he explains to viewers that the incident was a "tragic case" undergoing a thorough investigation "right to the end."

However, he refrained from issuing an apology for the victims.

On Tuesday, the Israeli army said it plans to launch an investigation into the air strike and vowed to "share our findings transparently".
