The Cruise ship was hit by an oil tanker while it was docking

Shocking images show the cruise ship almost on its side in the water, with a large tanker visible in the background. In another photo, passengers and crew sit along the railings of the capsized ship, now facing skyward as the vessel lies on its side.
According to an emergency response source quoted by the Guardian, rescue efforts were underway to pull people from the water. The source also suggested the tanker may have lost power before colliding with the American Heritage.
