A charter flight carrying 48 Japanese nationals and their family members who were evacuated from conflict-torn Sudan landed in Tokyo on Saturday morning, the government said.

The flight departed on Friday from a Self-Defense Forces base in Djibouti, a small African nation near Sudan, according to the Foreign Ministry.

One of the passengers, Naoyuki Kawahara, head of nonprofit organization Rocinantes that has been involved in providing medical support in Sudan, thanked those who assisted.

"Various people made efforts (to evacuate us). I am filled with gratitude," he told reporters at Tokyo's Haneda Airport.

As of Friday, 65 Japanese nationals and their family members of other nationalities have fled the northeast African nation for other countries since the conflict erupted. Some have returned to Japan by private means, the ministry said.

Most passengers on the flight that landed at Haneda Airport are those who initially fled overland from the increasingly dangerous Sudanese capital of Khartoum.

Upon reaching Port Sudan in the country's northeast, an SDF aircraft took them to Djibouti on Monday. Some of the 65 also escaped over a land border to neighboring Ethiopia.

Following the flight's departure, Defense Minister Yasukazu Hamada ordered SDF personnel dispatched to Sudan to return to Japan as their mission was complete.

Sudan has been plunged into chaos since fighting broke out in mid-April between the paramilitary Rapid Support Forces and the country's armed forces. Authorities in the country say more than 500 people have already died in the fighting.

A U.S.-brokered 72-hour cease-fire initially went into effect from midnight Monday, with both sides announcing its extension for a further three days into Sunday.

Despite the declarations, however, there have been reports of fighting in Khartoum.

Other countries, such as Germany, France and South Korea, have also evacuated their citizens from Sudan.
