According to the head of the UN refugee agency, Somali refugees in Kenya are some of the poorest and most vulnerable in the world.
Increasing numbers of malnourished young children are dying after trecking for weeks to receive emergency aid in what has become the "worst humanitarian disaster in the world", UNHCR chief Antonio Guterres said.
For Muslima Adan Hassan, 35, the journey was even more arduous. Two sons and a daughter died during their 35-day trek to Dadaab.
From the border, refugees have to travel 80km across the Kenyan desert to reach the camp, often on foot.
"We have cases where children are eaten by hyenas and lions," said Abdullahi Hussein Sheikh, one of the refugees.
Insecurity and hostility
In June, the number of new arrivals in Kenya's Dadaab refugee camp tripled to 1,300 people each day. International agencies have been unable to provide food aid inside Somalia due to insecurity and hostility from the Islamist rebel group, al Shabaab, which controls much of the country.
"I have visited many refugee camps in the world. I have never seen people coming in such a desperate situation," Guterres said on Sunday during a visit to the world's biggest refugee camp near the Kenya-Somali border.
Deaths of children under five increased six-fold in May, compared to the previous year, in Dagahaley, the northern section of the camp. Between 18 and 24 percent of new arrivals under five are malnourished.
"Many of the children are dying within 24 hours of arriving. They're arriving, we're screening them, we're sending them to our feeding programmes but even then it's not soon enough to catch them," Allison Oman, a nutritionist with UNHCR, said.
Emergency within an emergency
The United Nations has described the drought in the Horn of Africa as an emergency, one phase before famine. Some 10 million people are affected in a triangle straddling Kenya, Somalia and Ethiopia.
It says it is the worst drought in 60 years and almost a dozen aid agencies have launched massive appeals.
Somalia has had no effective central government for two decades, worsening the impact of recurring droughts. Al Shabaab has refused to allow food aid to be delivered in areas under their control, saying it encourages dependency.

Al Shabaab u-turn
Last week, al Shabaab made a u-turn and announced that humanitarian agencies were welcome in the country. The statement has been welcomed cautiously.
"It is absolutely essential to create the conditions for massive humanitarian aid to be distributed inside Somalia," said Guterres, describing Dadaab as "an emergency within an emergency".
The Kenyan government suspended plans to relocate thousands of refugees to a new site in October. It is concerned that militias use the camp to rest and recruit.
The situation is unlikely to improve before the onset of the rains season, which is expected in October.
