Millions of people across Turkey on Tuesday mourned the loss of more than 53,000 friends, loved ones and neighbors in the country’s catastrophic earthquake a year ago.

To mark what it calls the “Disaster of the Century,” the government arranged a series of events to commemorate the one-year anniversary of the disaster in southern Turkey.

In Antakya, the capital of the southern province of Hatay, angry crowds jostled with police as officials were led to the commemorations. Mayor Lutfu Savas was greeted with chants calling for him to resign, while Health Minister Fahrettin Koca was jeered and booed as he gave a speech.
