Ethiopians found in Malawi mass grave thought to have suffocated

Bodies tentatively identified as adults being secretly transported to South Africa on perilous southern route'

Dozens of Ethiopian people whose remains were found in mass graves in northern Malawi last month most likely suffocated to death while being secretly transported, investigators and campaigners believe.

The tragedy came amid a spate of incidents underlining the dangers faced by tens of thousands of people who entrust their lives to criminal networks that promise passage to South Africa, the most developed country on the continent.
