In April 2006 Chadian rebel leader Mahamat Nour Abdelkarim, having brought together several Chadian rebel movements under the banner of the Front Uni pour le Changement (United Front for Change, FUC), laid siege to N’Djamena. On 13 April 2006, 1,200 to 1,500 FUC rebels in 56 pickup trucks dashed hundreds of kilometers across Chad from bases in Darfur and the Central African Republic to fight pitched gun battles with Chadian security forces on the streets of the capital city. The fighting in Ndjaména lasted from 5 am to 11 am and included armored personnel carriers, technicals (4-wheel drive vehicles mounted with heavy weapons) and tanks, and was concentrated in the southeastern suburbs and at the Palais des Quinze, Chad's parliament, which rebel troops unfamiliar with the layout of the capital city mistook for the presidential palace.
