Institute War Clauses provides for loss or damage to the insured interest caused by hostilities, warlike operations, civil war, revolution, rebellion, insurrection, etc. but what is not generally appreciated is that cover only attaches as the interest insured is loaded on board the overseas vessel and terminates once it has been discharged at the far side.
War risks cover only attaches whilst the goods are at sea and does not attach whilst the goods are travelling on land. In addition, the cover specifically excludes loss or damage from the use of any atomic/nuclear weaponry.
