ISTANBUL, Turkey- Humanitarian agencies urged international and local communities, to work together to overcome challenges, in delivering basic supplies to those in urgent need in Yemen.

"We are witnessing the world's most complicated humanitarian crisis in Yemen, where at least 13 million civilians have been struggling against famine, drought and the war, all at the same time," Kerem Kinik, head of the Turkish Red Crescent Society, said, at a conference on humanitarian aid, in Istanbul.

Highlighting the severity of the situation in Yemen, Kinik spoke of hunger, malnutrition and scarcity of medical supplies, as among the most imminent threats facing the country.

"The Turkish Red Crescent Society has a permanent staff in the country, but we are having extreme difficulties in delivering our donations," said Kinik.

Kinik and his team will be heading for Yemen in the upcoming days, to hold talks with the relevant parties, about the distribution of humanitarian aid in the region.

Mette Petersen, head of Turkey's office of the International Federation of Red Cross and Red Crescent Societies, said that security and access to basic humanitarian aid supplies are the biggest challenges for local residents and the aid agencies operating in Yemen.

The International Committee of the Red Cross (ICRC) has delivered 100 million U.S. dollars to Yemen this year.

Katy Attfield, deputy head of ICRC's division for operations and partnership cooperation and coordination, said, her agency has been meeting with various authorities in Yemen, to make sure civilians have access to medical supplies, water and food.

"Most importantly, we are trying to find ways to protect the victims from the conflict," said Attfield.

The conference in Istanbul gathered multiple humanitarian aid organisations, including the UN refugee agency, United Nations High Commissioner for Refugees (UNHCR), the UN cultural agency, United Nations Educational, Scientific and Cultural Organisation (UNESCO), and Doctors Without Borders.
