Tropical Storm Irina killed three people when it lashed the Mozambique coast at the begin of the month, according to a final tally given by the government on Tuesday.

Deaths were recorded in the Cabo Delgado and Sofala provinces of the southern African country.

"In Cabo Delgado province, strong rains and winds in Montepuez district caused one death by electrocution," government spokesman Alberto Nkutumula told a media conference.

"In Sofala province there were unfortunately two deaths, 13 people were wounded, 989 houses were partially destroyed."

Irina passed over the Indian Ocean island of Madagascar last week, killing at least 72 people and leaving 78,000 homeless.

In South Africa's eastern city of Durban, beaches were closed as waves reached three metres (16-foot) and ships were ordered to remain in port.
