A head-on collision between a passenger train and a freight train in Greece has killed dozens of people and injured scores more.

Deputies with Harris County Sheriff’s Office are investigating two fatal crashes in east Harris County that left two people dead Saturday morning.

HOUSTON A good Samaritan jumped into action to help rescue two women trapped in a car following a pair of crashes in northwest Houston. That's when the good Samaritan said he saw a white Jeep that appeared to be speeding slam right into the back of the black car. Authorities said crews arrived at the scene and it took them, as well as the good Samaritan, about five minutes to pull the women out of the car. Witnesses said the man inside the Jeep was spotted throwing something out of the vehicle after the crash. Investigators said officers later found a bottle of alcohol at the scene, which is believed to be from that driver.
