Relatives of Ebola victims in Liberia defied government orders and dumped infected bodies in the streets as West African governments struggled to enforce tough measures to curb an outbreak of the virus that has killed 887 people.

In Nigeria, which recorded its first death from Ebola in late July, authorities in Lagos said eight people who came in contact with the deceased U.S. citizen Patrick Sawyer were showing signs of the deadly disease.

The outbreak was detected in March in the remote forest regions of Guinea, where the death toll is rising. In neighboring Sierra Leone and Liberia, where the outbreak is now spreading fastest, authorities deployed troops to quarantine the border areas where 70 percent of cases have been detected.
