A senior American diplomat in Mongolia has resigned, saying Washington's policies towards Iraq and North Korea are making the world more dangerous.
In a letter to the US State Secretary Colin Powell, Ann Wright - the deputy chief of mission at the US Embassy in the Mongolian capital, Ulan Bator - writes that the policy of pre-emptive attack on Iraq will provide justification for individuals and groups to pre-emptively attack America and its citizens.
Ann Wright, who is the third US diplomat to resign in protest at the Bush administration's Iraq policy, also criticises the lack of contact with North Korea since the crisis over its nuclear programme began last October.
