The Second Karabakh War and Caspian Energy Monday, 19 April 2021 April 19, 2021, the CACI Analyst On November 10, the second war in Nagorno-Karabakh ended with a Russia-brokered ceasefire agreement signed between Azerbaijan and Armenia. While the 44-day war caused severe damages to frontline settlements and civilian casualties on both sides, frequent missile attacks carried out by Armenia towards Azerbaijani cities and infrastructure beyond the frontline raised concerns not only in Baku but also in the EU regarding the security of vitally important energy infrastructure. The possibility of damages to energy infrastructure, particularly the Baku-Tbilisi-Ceyhan oil pipeline and the Trans-Anatolian Pipeline, would explicitly put the role of these pipelines in European energy security under question.
