A suicide bomber killed five people in a daring attack -- claimed by the Taliban -- inside the Information Ministry in the heart of the Afghan capital on Thursday, said the government. The Taliban said foreign advisers were the targets of the attack, which also involved an exchange of gunfire with ministry guards. Afghan President Hamid Karzai said the attack was carried out by the 'enemies' of Afghans. The deputy police chief for Kabul said a woman was also among those killed. A doctor at a hospital near the blast site said at least one person was killed and 18 wounded. The blast damaged part of the first floor of the ministry -- which lies several hundred metres away from the presidential palace in Kabul -- and forced authorities to evacuate ministry officials. Meanwhile, a Danish soldier was injured on Wednesday in a gunbattle in the southern Helmand province, said Denmark's Army Operational Command in a statement.
