On 1 October 1991, Dubrovnik was attacked by JNA resulting in a siege that lasted for seven months. The heaviest artillery attack was on 6 December with 19 people killed and 60 wounded. The number of casualties in the conflict, according to Croatian Red Cross, was 114 killed civilians, among them poet Milan Milišić. Foreign newspapers were criticised for placing heavier attention on the damage suffered by the Old Town than on human casualties. Nonetheless, the artillery attacks on Dubrovnik damaged 56% of its buildings to some degree, as the historic walled city, a UNESCO World Heritage Site, sustained 650 hits by artillery rounds. The Croatian Army lifted the siege in May 1992, and liberated Dubrovnik's surroundings by the end of October, but the danger of sudden attacks by the JNA lasted for another three years.
