The short video clip shows Mia Schem lying on a bed, her right arm being bandaged by someone out of the frame. A long, fresh scar is clearly visible.

Schem, a 21-year-old French-Israeli woman, is being held hostage by the militant group Hamas in the Gaza Strip. The video released by Hamas on Monday is the first footage of any of the dozens of people held in the enclave.

Speaking into the camera, Schem, who looks pale, but is sitting up straight with her head held high, says she was injured and taken to Gaza, then pleads to be returned to her family.

As she speaks, loud rumbling can be heard in the background.

Speaking to reporters on Tuesday in Tel Aviv, Schem’s mother urged the government and world leaders to bring her daughter back home.
