The South Yemen insurgency is a term used by the Yemeni government to describe the protests and attacks on government forces in southern Yemen, ongoing since 27 April 2009, on South Yemen's independence day. Although the violence has been blamed on elements within the southern secessionist movement, leaders of the group maintain that their aims of independence are to be achieved through peaceful means, and claim that attacks are from ordinary citizens in response to the government's provocative actions. The insurgency comes amid the Shia insurgency in the country's north as led by the Houthi communities. Southern leaders led a brief, unsuccessful secession in 1994 following unification. Many of them are involved in the present secession movement. Southern separatist insurgents are active mainly in the area of former South Yemen, but also in Ad Dali' Governorate, which was not a part of the independent southern state. They are supported by the United Arab Emirates, even though the UAE is a member of the Saudi Arabian-led coalition working to support the Yemeni government under President Abdrabbuh Mansur Hadi.
