Kale borroka (, "Street Fighting") refers to urban guerrilla actions carried out by Basque nationalist youth who are integrated into the abertzale left. Along with ETA, the kale borroka is the only remaining armed faction of Basque nationalists in the Basque Conflict.
Their tactics include: attacking offices of Spanish parties, especially the Spanish Socialist Workers' Party and People's Party, but also other parties such as Basque Nationalist Party and Navarrese People's Union, attacking the property of people linked to these groups (burning cars, attacking housing), attacking and destroying ATMs, attacking bank offices, buses, and rioting at demonstrations, using molotov cocktails, burning trash containers, etc.
During ETA's ceasefire from March 2006 to 2007, the kale borroka did not cease, but it has been decreasing since it peaked in the mid 1990s.
