The UN Security Council on Sunday strongly condemned a terrorist attack on a tourist bus in south Sinai in Egypt, which killed four people, including three South Korean tourists It called for the perpetrators to be brought to justice. "The members of the Security Council condemned in the strongest terms the terrorist attack," the 15-nation UN body said in a statement. The Security Council also extended condolences to the families of the victims and expressed sympathy to those injured in this "heinous act," and to the people and governments of Egypt and the Republic of Korea. A bomb exploded in the front part of a bus carrying South Korean sightseers near an Egyptian border crossing to Israel in southern Sinai on Sunday, killing three tourists and an Egyptian driver. It was the first attack on tourists since the ouster of President Mohamed Morsi by the Egyptian army in July that sparked civil unrest and a spate of attacks across the country, which have mainly targeted security forces. "The members of the Security Council reaffirmed that terrorism in all its forms and manifestations constitutes one of the most serious threats to international peace and security," the statement said, adding that terrorist acts need to be combatted by all means. UN Secretary-General Ban Ki-moon earlier Sunday also strongly condemned the attack. . .
