JERUSALEM, Apr. 4 (Reuters) - Israel said on Thursday it would adjust tactics in the Gaza war after killing seven aid workers in air strikes its military has acknowledged were a major mistake, and that inquiry findings would be made public soon.

Monday's incident has stoked Western anger at the mounting civilian toll in the Palestinian enclave, especially as the slain World Central Kitchen staff included Australian, British and Polish citizens along with a U.S.-Canadian dual national.

At least 196 humanitarian workers have been killed in Gaza since October, according to the United Nations.

Israel's leaders have voiced sorrow over what the military called a "grave mistake" after the misidentification of a WCK convoy at night in a complex combat zone.

Charity founder, chef Jose Andres, said the convoy was "systematically" targeted even though Israel's military was aware of his staff's movements.

Asked to respond, Israeli government spokesperson Raquela Karamson said during a media briefing: "This was unintended."

"Clearly something went wrong here, and as we learn more and the investigation reveals exactly what happened, and the cause of what happened, we will certainly adjust our practices in the future to make sure this does not happen again."

She said publication of the investigation's findings could take weeks. But the chief Israeli military spokesperson, Rear Admiral Daniel Hagari, appeared to give a much shorter timeline.

An investigators' report was given to Prime Minister Benjamin Netanyahu and Defence Minister Yoav Gallant on Thursday, Hagari said in a televised statement.

"And I believe that, after we present this to the ambassadors from the respective countries, and to the members of the WCK organisation, we will make it public in a clear, transparent manner - and that will happen soon," he said.
