Aid group Doctors Without Borders is pulling out of Somalia after 22 years because of attacks on staff.
The group, also known by its French name Médecins Sans Frontières (MSF), said that armed groups and civilian leaders in Somalia "support, tolerate or condone" killings, assaults and abductions of aid workers.
It said the pull-out will cut off hundreds of thousands of Somali civilians from humanitarian aid.
It comes a month after two Spanish workers from Doctors Without Borders were released after nearly two years in captivity in Somalia.
MSF's international president said that respect for humanitarian principles no longer exists in there.
