About 20 others were injured when the truck they were in collided with another vehicle yesterday, the Swaziland Solidarity Network said in a statement. The young women and girls were allegedly travelling on the back of an open truck, the rights group said.
Police in Swaziland, a small mountainous country of 1.4 million people bordering northeastern South Africa and Mozambique, discouraged reporting on the accident, said the group. Photographers were prevented from taking pictures at the scene, said a Swazi journalist who insisted on anonymity for security reasons.
"You don't hide a death," said Lucky Lukhele, spokesman for the Swaziland Solidarity Network. Members of the Swaziland Defense Force alerted the rights group to the accident, Lukhele said, adding that he expected the death toll to rise.
The females were travelling on a highway between the Swazi cities of Mbabane and Manzini, when the truck carrying them smashed into another vehicle and was then hit in the rear by a second truck, the Times of Swaziland reported.
The girls and young women were on their way to the Swazi king's royal residence for the annual reed dance. About 40,000 participate in the eight-day ceremony in which they sing and dance, often bare-breasted, as they bring reeds to reinforce the windbreak around the royal residence, a government website said.
Swaziland is Africa's last absolute monarchy, ruled by King Mswati III since 1986. Swaziland held parliamentary elections in 2013, but many international observers say the electoral process is manipulated to prolong the king's hold on power. According to the king, Swaziland's image has been damaged by misinformation.
