According to another report, shots were fired at the Israelis.

Shoshi, an eyewitness, told Voice of Israel Radio “We went through passport control and representatives were waiting to deposit us in buses to the hotels. We put the bags in the trunk, and after a few minutes, the bus exploded in flames. Then we returned to the terminal, and now we are trying to determine who is missing and who is dead.”

Shoshi’s son added: “People who survived the explosion escaped from the window, and could not step over the bodies. The bus was shattered on both its sides.”
