Two people were killed in Madagascar after Cyclone Belna landed in the northwest of the country, causing heavy flooding and displacing hundreds, local authorities said on Tuesday.
The tropical cyclone hit the impoverished island nation's Boeny region on Monday after brushing past the island of Mayotte and the Comoros archipelago.
"A child and an elderly person were unable to save themselves" after a dam collapsed in Soalala, said the head of Madagascar's National Office for Disaster Risk Management (BNGRC), Elack Andriakaja.
The cyclone brought torrential rain and reached a maximum wind speed of 180 kmph, tearing off roofs and causing widespread damage.
The BNGRC said 1 300 people were displaced in the town of Soalala and 172 - including 120 children - in the port city of Mahajanga.
"The cyclone will disappear before long but danger from flooding has not yet been averted," Andriakaja said, adding that access by air remained "complicated".
The World Health Organization (WHO) has distributed medicines for 1 500 people and supplies will be sent out via boat on Wednesday.
Cyclone Belna bypassed Mayotte on Sunday after initial forecasts put the French island in its direct path.
Neither Mayotte nor the Comoros are reported to have suffered significant damage.
