African Union Mission in Sudan The African Union Mission in Sudan ( AMIS ) was an African Union ( AU ) peacekeeping force operating primarily in the country ' s western region of Darfur with the aim of performing peacekeeping operations related to the Darfur conflict . Originally founded in 2004 , with a force of 150 troops , by mid - 2005 , its numbers were increased to about 7 , 000 . Under United Nations Security Council Resolution 1564 , AMIS was to " closely and continuously liaise and coordinate . . . at all levels " its work with the United Nations Mission in Sudan ( UNMIS ) . AMIS was the only external military force in Sudan ' s Darfur region until UNAMID was established . It was not able to effectively contain the violence in Darfur . A more sizable , better equipped UN peacekeeping force was originally proposed for September 2006 , but due to Sudanese government opposition , it was not implemented at that time . AMIS ' mandate was extended repeatedly throughout 2006 , while the situation in Darfur continued to escalate , until AMIS was finally replaced by UNAMID on December 31 , 2007 . Overview ( 2004 - 2006 ) . AMIS originated in early July 2004 , when both the African Union and European Union sent monitors to monitor the Darfur crisis cease - fire signed in April 2004 . In August 2004 , the African Union sent 150 Rwandan troops in to protect the ceasefire monitors . It , however , soon became apparent that 150 troops would not be enough , so they were joined by 150 Nigerian troops . During April 2005 , after the government of Sudan signed a ceasefire agreement with Sudan People ' s Liberation Army which led to the end of the Second Sudanese Civil War , the AMIS force was increased by 600 troops and 80 military observers . In July 2005 , the force was increased by about 3 , 300 ( with a budget of 220 million dollars ) . In April 2005 , AMIS was increased to about 7 , 000 ( at a cost of over 450 million dollars ) , and , this remains its projected strength . International response ( 2004 ) . In September of that year , the United Nations Security Council passed Resolution 1564 , which gave Sudan the ultimatum of accepting an expanded AU force or facing sanctions of their oil industry . The African Union had hoped to have 3 , 000 more additional troops in place in the region sometime in November , but could not do so because of a lack of money and difficulty with logistics . The AU resolved that all parties involved would wait on the AU ' s Peace and Security Council to meet on October 20 , 2004 and decide on the expanded duties and numbers of the force . It was decided that these Nigerian and Rwandan AU troops would be deployed by October 30 . Attempted reconciliation ( 2005 ) . On November 9 the government of Sudan and the two leading rebel groups , the Justice and Equality Movement ( JEM ) and the Sudanese Liberation Army ( SLA ) , signed two short term peace agreement s aimed toward progress in ending the conflict . The first treaty established a no - fly zone over rebel - controlled areas of Darfur , a measure designed to end the Sudanese military ' s bombing of rebel villages in the region . The second accord granted international humanitarian aid agencies unrestricted access to the Darfur region . The accords were the product of African Union sponsored peace talks in Abuja that began October 25 , 2004 . To support the Comprehensive Peace Agreement signed by the government of Sudan and the Sudan People ' s Liberation Movement on January 9 , 2005 , to perform certain functions relating to humanitarian assistance , protection , promotion of human rights , and to support AMIS , the UN Security Council established the United Nations Mission In Sudan ( UNMIS ) under Resolution 1590 on March 24 , 2005 because the Security Council deemed the situation in Darfur to be a " threat to peace and international security . " July 2005 saw that there had been no major conflicts since January , and the numbers of attacks on villages was dropping . At the time , there were about 3 , 000 AMIS troops to keep the peace , and more due to arrive in the coming months , eventually reaching 7 , 000 troops in April . In keeping with a decision made by the Peace and Security Council , Nigeria sent a battalion of 680 troops on Wednesday , July 13 , 2005 , with two more coming soon thereafter . Rwanda will send a battalion of troops , Senegal , Gambia , Kenya and South Africa will send troops as well . Canada is providing 105 armoured vehicles , training and maintenance assistance , and personal protective equipment in support of the efforts of the AMIS . On September 15 , a series of African Union mediated talks began in Abuja , Nigeria between representatives of the Sudanese government and the two major rebel groups . However , the SLM faction refused to be present and according to a BBC reporter the SLM " will not recognise anything agreed at the talks . " After a government - supported Arab militia attacked the Aro Sharow refugee camp on September 28 , killing at least 32 , the African Union on October 1 accused both the Sudanese government and rebels of violating the ceasefire agreement . The Associated Press reports the African Union as condemning the government ' s acts of calculated and wanton destruction that have killed at least 44 people and displaced thousands over two weeks . Attacks on the African Union ( 2005 ) . Forces from the Sudanese rebel group , the Justice and Equality Movement ( JEM ) , have assisted in liberating 38 African Union ( AU ) personnel that were taken hostage on October 9 . The kidnapped – which consisted of the original 18 hostages , and later a 20 man rescue team – were released on October 10 . Initially , two hostages remained but were freed following a reported shootout with the kidnappers . A splinter group of JEM was blamed for the attack , but Mohamed Saleh , the head of the dissident faction , has denied the allegations . Saleh was the military head of JEM when it signed a ceasefire agreement in April , but later split with the group ' s leadership . It is said that he now commands " thousands " of troops in the Darfur region , and is looking for a seat at the ongoing peace talks . He accused the AU of taking sides , and stated that he will not honour the ceasefire . While speaking with Reuters , Saleh said , " We want the AU to leave , and we have warned them not to travel to our areas . We don ' t know and don ' t care what is happening to the AU , they are part of the conflict now . " Violence in the region has continued to rise . According to BBC correspondent Jonah Fisher , hostilities toward AU peacekeepers are becoming more common . It has been noted that aid agencies are refusing to travel with African Union personnel , stating that the mere presence of the peacekeepers may draw fire . Kofi Annan , at a press conference in Geneva , responded to the rising violence by suggesting aid to the region may be partially suspended . " Both rebels and government must understand that , if these incidents continue , it will impede humanitarian assistance and delivery . " This marked the first time the African Union has suffered casualties in the region . Three personnel were killed in attacks believed to be perpetrated by the Sudan Liberation Army ( SLA ) . Despite the violence , the SLA , JEM , and the AU have promised to continue the peace talks which are being held in Abuja . In November 2005 in response to attacks on African Union troops the government of Sudan agreed to the deployment of 105 armoured personnel carriers from Canada which should arrive on November 17 , also another round , the seventh , of peace talks started on November 21 , 2005 . Failed UN handover and mandate extensions ( 2006 - 7 ) . On 31 March 2006 the mandate of AMIS would have run out , with the African Union force already on the ground to be incorporated into a UN peacekeeping mission . Nevertheless , during a March 10 , 2006 meeting of the African Union ' s Peace and Security Council , the Council decided to expand the mission for six months until 30 September 2006 . On August 31 , after United Nations Security Council Resolution 1706 failed to see the implementation of its proposed UN peacekeeping force of 20 , 000 due to opposition from the government of Sudan , on October 2 the AU extended AMIS ' mandate further , until December 31 , 2006 , and then again until June 30 , 2007 . In May 2007 , the AU declared that AMIS was on the point of collapse . In previous month seven peacekeepers had been killed , while lack of funding had caused soldiers ' salaries to go unpaid for several months . Rwanda and Senegal warned that they would withdraw their forces if UN member nations did not live up to their commitments of funding and supplies . John Predergast of the International Crisis Group noted , The big money problem is that the Americans and the Europeans promised over the last decade that as long as the Africans deployed in these kinds of situations , we would pay for the soldiers and equip them . And we haven ' t done it . On 31 July 2007 , the United Nations Security Council finally approved by United Nations Security Council Resolution 1769 the mandate for UNAMID , which was to take over operations from AMIS by 31 December 2007 . AMIS finally was merged into UNAMID on 2007 - 12 - 31 . 30 September 2007 raid on AU base . On 30 September 2007 , a major raid on an AU base , mounted by approximately 1 , 000 Sudan Liberation Army rebels , claimed the lives of at least 10 peacekeepers and wounded many more . At least 50 personnel were initially unaccounted for , but were later recovered . The attack occurred just after sunset in the northern part of Darfur province , and comes amid increasing tensions and violence between the separatist rebels and foreign peacekeepers , with the latter often accused of abrogating their neutrality and bias towards the central government .
