MAPUTO, May 26 (News Agencies) - Mozambique began three days of mourning Sunday, May 26, following the death of nearly 200 people in a train crash, the worst in more than a decade in the southern African country.

Rescue workers had by Sunday recovered all the dead and injured from the site of the crash Saturday that killed at least 195 and left 166 wounded, according to Transport Minister Tomas Salomao Agence France-Presse (AFP) reported.

The accident was the worst in 12 years of railway transport in Mozambique, according to AFP records. The last major train crash was in 1990 in the northern port town of Nacala where 106 people died.

President Joaquim Chissano was Sunday touring the wreckage of the overturned train, whose wagons have been removed from the tracks to open the line to other trains.

"The site has now completely cleared leaving the line in business again," said Salomao, who led the rescue operation following the accident at Pessene, in Moamba district, 40 kilometers (25 miles) west of the capital Maputo.

Opposition RENAMO leader Afonso Dhlakama had visited the scene of the crash Saturday.

Salomao, speaking on state radio, said a final casualty toll would be released later Sunday.

The government declared three days of mourning beginning Sunday, with flags flying at half-mast.

The cause of the accident is not yet known, but preliminary findings by government investigators indicated human error.

Hospitals are still scrambling to find doctors and blood supplies with many of the wounded in critical condition.

Salamao said the immediate priorities were to save lives and assist the families of the dead in identifying and burying their loved ones.

Authorities have launched an appeal for blood donations.

Maputo Central Hospital, which is treating the injured, has been dangerously short of blood for months. In December, the hospital completely ran out of blood and had to launch a door-to-door campaign to find donors.

The hospital has recalled all doctors on vacation and ordered all medical students to report for duty to help treat the victims.

The tragedy has placed an enormous strain on the health care system in one of the world's poorest countries.

Both President Chissano and Dhlakama visited the wounded in hospital on Saturday.

"This is a problem of my country, a problem of all of us, and that is why I am here", Dhlakama, whose RENAMO fought the government during a 16-year civil war which ended in late 1992, told reporters.

Chissano praised the efforts of the "hard-working doctors" operating with limited resources and for the positive response of civil society to appeals for assistance.

The train was headed from Ressano Garcia, on the border with South Africa, to Maputo carrying mostly women traders.

A government statement said the investigation into the cause of the accident was continuing.
