MNJ has claimed a series of attacks on the Nigerien Military and foreign economic interests since February 2007. The organization has taken responsibility for attacks which have killed 45 people and seized several Nigerien soldiers. In 2008, the MNJ claimed to have some 3,500 fighters, many of them
defectors from the Nigerien military. In June 2007, the MNJ attacked northern Niger's main airport at
Agadez and overran an army outpost in the Aïr Mountains taking over 70 Nigerien soldiers prisoner. On 6 July 2007, the MNJ kidnapped a
Chinese nuclear engineer working for
China Nuclear Engineering and Construction Corps, holding him for about 10 days until releasing him to the Red Cross. The company had been prospecting for
uranium for some time in Teguidan Tessoumt in cooperation with the Niger government, and MNJ wanted them to cease their operations. On 22 June 2008, the MNJ kidnapped four employees of Areva, the French state nuclear corporation which has been exploiting northern Niger's uranium for over forty years. The French nationals were released to the Red Cross three days later. ==Leaders==
