PORT MORESBY

A US academic has been gang-raped by an armed mob in Papua New Guinea, barely a week after an Australian was killed and his friend sexually assaulted by a group of men. The incidents come after a brutal spate of sorcery-related crimes that have sparked condemnation from the United Nations and undermined the poor Pacific country's standing as a destination for tourism and investment.

In the latest case, the white academic told AFP that she was attacked on Friday while conducting research on birds and the impact of climate change in a remote forest on Karkar Island in Madang province.
