Yemen's Coast Guard has so far found the bodies of 28 African migrants, days after two boats carrying about 80 infiltrators, mostly Ethiopians, sank off the country's coast, a security official said.

The bodies were of the migrants onboard the boat that carried 46 people, all Ethiopians, and capsized near the Bab Al-Mandab Straits, the unidentified official at the security department of the Straits said.

"Early today 8 bodies were washed ashore at Al-Suwaida'a coast, a day after 17 bodies were buried in the same area. Meanwhile, rescue operations are continuing," the official added.

On the accident day, three bodies were found, the Interior Ministry said.

An official at the Yemeni Red Crescent confirmed the figure of those recovered.

"The bodies were badly damaged that we could not identify who was a Somali or Ethiopian. We just buried the bodies," the official said.

According to the UNHCR in the country five survived, two Somalis and three Ethiopians, out of almost 80 Africans, who were onboard the two boats, which capsized in bad weather off Lahj in the south and near Bab Al-Mandab in the Red sea.

The accidents came as Africans, from Somalia and Ethiopia fleeing deteriorating situations there, continue to defy death crossing the dangerous sea into Yemen almost daily.

The UNHCR said the flow of African migrants rose by 50 per cent in 2009, coinciding with recent Yemeni statistics suggesting the number of the Africans, who have already arrived in the country, exceed one million people.
