The work is a study of the cross-border terrorism that has been bedeviling the developing countries, with emphasis on Africa and the Indian subcontinent. The work studied the concepts of international terrorism and cross-border terrorism and noted that international terrorism came to the attention of the international community with the brutal assassination of King Alexander of Yugoslavia and Mr. Louise Barthou, the French foreign minister in 1934. The study found that the causes of cross-border terrorism is a result of political and economic instability that have beset the developing countries as a result of weak and illegitimate governance, economic downturn, corruption, mismanagement of national resources, ethno religious intolerance and extremism of ideas, lack of effective border control etc. The solution proffered by the study include that states should have a more effective border control with the help of CCTV and security personnel that are up to their duty. Again, and more importantly states should down play difference in ethnicity and religion and embrace our shared humanity. Developing countries must endeavour to strengthen their economies by fighting corruption, mismanagement of resources, and prebendalism. The study adopted expofacto as its research design. It deployed relative deprivation and frustration – aggression theory as its theoretical framework. Its method of data collection was secondary data collection. The study employed relational content analysis as its method of data analysis.
