Despite signing the Kano Accord, Libya was incensed that the GUNT did not include any of the leaders of the Volcan Army and had not recognized Libyan claims on the Aouzou Strip. Since 13 April there had been some minor Libyan military activity in northern Chad, and support was provided to the secessionist movement in the south. However, a major response came only after 25 June, when the ultimatum of Chad's neighbors for the formation of a new, more inclusive coalition government expired. On 26 June, 2,500 Libyan troops invaded Chad, heading for Faya-Largeau. The Chadian government appealed for French help. The Libyan forces were first stymied by Goukouni's militiamen, and then forced to retreat by French reconnaissance planes and bombers. In the same month, the factions excluded by the GUNT founded a counter-government, the Front for Joint Provisional Action (FACP), in northern Chad with Libyan military support.
