nal operations, such as bank robberies, prompts people to perceive that the state is losing the battle against criminals. 232. The last category of causes of violence has an international character. Crossborder crimes involve Mozambican nationals and/or nationals of other countries acting exclusively, or in partnership, to carry out criminal activities across national boundaries. Also in this category are immigrants who are increasingly being perceived to be involved in unspecified criminal activities. The CSAR reports that Mozambicans believe that Maputo and Nampula host large numbers of immigrants, many of whom are believed to have gained illegal entry into the country with the connivance of corrupt public servants. Uncertainty about the nature and legality of the businesses in which immigrants engage, and their apparent success within a relatively short time after their arrival, causes suspicion among locals. 233. The CSAR shows that there are formal and informal mechanisms in Mozambique for the prevention, management and resolution of intrastate conflicts. The informal mechanism comprises traditional rulers, while the formal mechanism consists of all security agencies and the courts. Interstate conflicts are prevented or managed by mechanisms established under the SADC. II. Findings of the CRM 234. The government has recorded tremendous achievements in implementing the GPA and setting the context for peace, constitutional rule and multiparty democracy (Box 3.2). The disarmament, demobilisation and rehabilitation (DDR) of ex-combatants have been formally concluded under the supervision of the United Nations Operation in Mozambique (UNOMOZ). This was a major confidence building-block of the peace process, as it symbolically signalled a farewell to arms and the embracing of national unity and reintegration.
