CAIRO (AP) — A defense lawyer in Egypt’s trial of three journalists and 17 others has cross-examined a witness over his analysis of footage shot by the Qatar-based Al-Jazeera English that the prosecution says undermines national security.

The footage wasn’t seen in Monday’s session. But lawyers said it included interviews with politicians and a soccer game. The prosecution’s claim is that Al-Jazeera footage is edited to exaggerate unrest in Egypt. They accuse al-Jazeera of bias toward Islamist President Mohammed Morsi, ousted by the military in July after mass protests.
