Doctors Without Borders CEO Claire Magone accused Israeli troops of shooting at their convoy.
"These accusations are very serious, because what happened is very serious," Claire Magone said in an interview with franceinfo radio.
The head of the organization claimed the responsibility of the Israeli army in the firing of a convoy on November 18 in the Gaza Strip, which killed two people, on the organization's convoy trying to move to the south of the country.
Claire Magone assures that the convoy of "civilians and humanitarian supplies was clearly identified".
The organization also said it had informed the Israeli authorities about the convoy.
Two days later, she said, the Israelis destroyed the same vehicles that were parked in front of the organization's clinic.
"The Israeli army destroyed the cars with a bulldozer and set the cars on fire, resulting in the burning of the clinic where the teams took shelter," the organization's director general said.
