Italian luxury cruise ship Costa Concordia ran aground near a Tuscan island and keeled over on Friday, leaving at least 11 people dead and about two dozen still missing four days later.
Here is a timeline of the disaster, based on official statements and eyewitness accounts.

The first port-of-call on the seven-day cruise was to be Savona in northwest Italy, with stops including Marseille and Barcelona.
