International Humanitarian Law in Urban Warfare

Urban environments have increasingly been at the forefront of a number of armed conflicts. This should come as no surprise, since an urban setting has the capability of producing a number of advantages for the defending side by negating any numerical or mechanical advantage the opposing force may have. In addition, cities make it easier for combatants to hide and blend in with the civilian population and conduct irregular military activities. While this might constitute an advantage for the conduct of military operations, it means that civilians could become entrenched in a combat situation. Therefore, it is of paramount importance that all sides of a conflict maintain the utmost regard for international humanitarian law. In line with the current conflict in Ukraine, this contribution will focus on the scope of international humanitarian law in an international armed conflict, between two or more internationally recognised States. As such, this InfoFlash aims to provide a general overview of three of the main principles which are of special interest in an urban environment: the principles of distinction, proportionality, and precaution.

Autonomous weapons systems incarnate one of the most debated evolution in warfare. War is based upon a simple negative definition of a lawful targets and the conduct of hostilities. Hence, only an authorised party can legally kill another according to the jus in bello. However, with the development of new technologies, legal questions arose around the use of lethal autonomous weapons systems in international or non-international conflicts.

New Means of Warfare against Orbital Targets, a thin line between Compliance and Violation of the International Conflict Law

In the context of the new attention given by the states to the three strategic "oceans", the air and space domain embodies duality. On the air side, the rule of law is already quite clear. The real issue revolves around the space side of the subject. Given the growing need for space facilities to ensure a coherent military strategy, force projection, surveillance, intelligence, etc. It is necessary to address the legality of conducting an attack in orbital space against such installations.

The Role of Conventional Forces in Modern Warfare and the European need of Innovation and Harmonisation

In recent years hybrid and cyber warfare have become the main focus in the defence sector. New technologies mean new threats, adapting defence capabilities to innovation is critical to maintain high-efficiency levels. During the NATO Madrid summit, which took place on 29th-30th, the issue of cybersecurity and disinformation was on the agenda, and necessary steps were included in the final declaration and in the new Strategic Concept. NATO announced a new defence and deterrence posture across the cyber domain to fight against new threats and challenges and stressed the necessity to increase resilience. However, the last events that occurred in our continent seem to be highlighting an unavoidable fact: conventional forces still play a fundamental role.
