Rocket falls in Gaza after Color Red siren sounded in South

A 'Color Red' siren sounded Friday morning in Israel's Gaza-border communities, indicating an incoming rocket from Gaza. Shortly thereafter, it became clear that a rocket had not exploded in Israeli territory, but rather fell in Gaza. The incident was believed to have been a failed launch attempt that landed inside the Strip.

Meanwhile, on Thursday night a series of nearly simultaneous explosions occurred in Hamas-controlled Gaza, targeting officials from Palestinian President Mahmoud Abbas' Fatah. Letters claiming to be from a Gaza offshoot of the Islamic State group, warned Fatah leaders to stay in their homes until November 15. There were no casualties and Fatah and Hamas consider the letters to be forgeries.
