Israeli defense officials expressed fear on Friday that the viral video clip showing Border Police officers shooting a Palestinian woman armed with a knife at the Afula bus station could touch off further unrest and lead to more violence.In the clip, police officers and security guards are seen aiming their weapons at the woman, who had pulled out a knife and refused repeated instructions to place it on the ground. Seconds later, the woman is shot in her lower body. She was listed in moderate condition and transported to Poriya Hospital in Tiberias for treatment."This clip has reached every Palestinian house," a senior defense source told The Jerusalem Post's Hebrew-language sister publication Ma'ariv. "It is being depicted throughout the world as an execution."
