The radical Islamic group al-Shabaab has reportedly banned several Christian aid groups from Somalia.
The militant group accused World Vision, Adventist Development and Relief Agency (ADRA), and Diakonia - all of which have offices in southern Somalia - of promoting Christianity in the Muslim country.
"Acting ... under the guise of humanitarian work, these organizations have been spreading their corrupted ideologies," the radical Islamist group said.
Al-Shabaab, which is connected with al Qaeda, has threatened that "appropriate disciplinary measures" will be taken against anyone who helps the Christians.
World Vision and ADRA have since ceased their work in the area, but criticized the radical Islamic group for making false accusations.
"World Vision Somalia received a demand today from al-Shabaab to close operations in Somalia. World Vision is surprised and disappointed by the move, based on false accusations of spreading Christianity," World Vision officials said.
