A Polish woman who was among the first injured in the Tunisia museum thought she was dying from her wounds.

Jadwiga Olszewska and her husband had just left National Bardo Museum in Tunis on Wednesday when she heard shots.

"Someone shouted: 'Drop to the ground' and I dropped, but suddenly I felt strange warmth and pain. My arm was lying on my belly in a strange position and I had a wound in my belly," Olszewska said in a trembling voice in an interview aired on TVN24 Friday.

"I thought I was dying," she said from her hospital bed in Tunis, with her right elbow bandaged and forehead dressed. "My husband was shouting to me to hang on. He was hit on the leg. I was trying to stop the blood with a scarf I had."

"Some time later, some soldiers came and I didn't know if they wanted to help us or finish us off," she added. "They dragged me to a tree and propped up against it. I don't remember anything else. I must have passed out."

"It was terrible. I never went through anything like that in my life," Olszewska said.

From a nearby hospital bed, her husband, Janusz Olszewski, said he saw a "short black figure" when the shooting began, running with something like a gun in his hand.

The couple was flying back to Poland on Friday on a special plane with medics, which was sent by the Polish government.

Poland's Foreign Ministry said Friday that a third fatality has been identified, raising to three the number of Poles killed in the attack. Another 10 Poles were injured. No names have been released.
