( CNN ) -- Border skirmishes between Thailand and Cambodia flared for a second day in an ongoing dispute over an ancient Hindu temple , a Thai military official said Wednesday . There were several exchanges of gunfire overnight , according to Col. Sansern Kaewkumnerd , a Thai military spokesman , who said the exchanges were brief . Some hand grenades were thrown and one Thai soldier was injured , he said . The Asian neighbors have been urged by the U.N. Security Council to end their dispute over Preah Vihear temple . The council issued a statement on Monday , following a closed-door session on the conflict that included representatives from both sides and the Association of Southeast Asian Nations ( ASEAN ) . `` The members of the Security Council called on the two sides to display maximum restraint and avoid any action that may aggravate the situation , '' said the statement , read by Ambassador Maria Luiza Ribeiro Viotti of Brazil , which holds the monthly presidency of the 15-member body for February . `` The members of the Security Council further urged the parties to establish a permanent ceasefire and to implement it fully and resolve the situation peacefully and through effective dialogue , '' she said . Border skirmishes , which started earlier this month , have killed five people , including members of the military and civilians , a statement from ASEAN said , adding that each nation accuses the other of firing first . The clashes stem from a longstanding conflict related to the 11th-century Preah Vihear temple . The building sits on a cliff in Cambodian territory , but the most accessible entrance to the site is on the Thai side . In a letter to the United Nations last week , Cambodian Prime Minister Hun Sen said that in addition to the human toll the fighting was taking , the temple had suffered damage . Conflict over the site has taken place periodically for years . In 1962 , the International Court of Justice in The Hague , Netherlands , ruled that the site was in Cambodia , adding that the structure was `` an outstanding masterpiece of Khmer architecture . '' But Thailand says the 1.8-square-mile ( 4.7-square-kilometer ) area around Preah Vihear was never fully demarcated , and blames a map drawn at the beginning of the 20th-century during the French occupation of Cambodia . In July 2008 , the United Nations approved Cambodia 's application to have the temple listed as a World Heritage Site , meaning the U.N. believes the place has outstanding universal value .
