The Port of Iskenderun in southern Turkey sustained heavy damage on Monday.

The port, located on the Mediterranean coast in the southern province of Hatay, was damaged due to the earthquake that struck Turkey and neighboring Syria.

"The Port of Iskenderun remains closed until further notice, as teams look to repair the significant damage caused by the disaster and subsequent fire," shipping group AP Moller Maersk said in a statement Tuesday. "We are currently unable to say exactly how long operations will be stopped at the port, but we will keep customers informed of the latest developments as soon as possible."

Maersk said it was not accepting any new bookings to or from the port and were developing contingency plans with nearby hubs.

Christian Atsu, a professional soccer player for the Turkish team Hatayspor, was among the more than 8,000 people rescued from the rubble in Turkey, according to his team.

Atsu was injured in the quake. The sporting director for Atsu’s team remains under the rubble, according to a team vice president.

Atsu was on Ghana's 2014 World Cup team and also played for Newcastle United in the English Premier League.

At least 150,000 people in Turkey have been left homeless due to Monday’s deadly earthquake and aftershocks, according to the International Committee of the Red Cross.

Some 23 million people in Turkey and Syria have been affected by Monday’s massive earthquake and powerful aftershocks, according to Turkish and Syrian authorities.

About 13.5 million of them are in Turkey, according to Turkish Minister of of Environment, Urbanization and Climate Change Murat Kurum.

Rescue efforts have been hampered by snow and freezing temperatures in the 10 affected Turkish provinces, Kurum said during a press conference Tuesday in the city of Gaziantep, near the quake’s epicenter.

The United States is “ramping up” assistance to Turkey and Syria, White House spokesperson John Kirby said Friday.

“In Turkey, a USAID Disaster Assistance and Response Team is already on the ground. And two of our most highly trained urban search and rescue teams are conducting operations in support of Turkish rescue efforts in Adana -- one of the hardest-hit areas inside the country,” Kirby said. “These teams have nearly 200 personnel combined between them, specialized equipment and canine support dogs, as well.”

Kirby said they’ve been able to “expand their operational reach with the support of U.S. military Blackhawk helicopters” to try and get around the extensive damage to roads and bridges.

“To date, they have been able to cover more than 630 sites across Adana [in Turkey],” Kirby said. “In Syria, our humanitarian partners continue to urgently scale up response efforts to reach people in need. That work will include, or has included, chartered flights that are transporting essential medical supplies and teams distributing hot meals and other food.”

The United Nations and its partners have successfully completed two humanitarian convoys into northwest Syria, Kirby said. One partner delivered 14 additional truckloads of supplies through the Bab-al-Hawa Crossing on the Turkey-Syria border, “totaling now 20 trucks of critical medicines, food and water to people in need over the last two days,” he said.

Kirby said U.S. sanctions imposed on Syria “will not prevent or inhibit prohibiting humanitarian assistance.”
