NAIROBI - A blast at an explosives store wrecked buildings and caused "massive damage" to an industrial zone on the Seychelles' main island Mahe, officials said, prompting the president to declare a state of emergency on Thursday.

The blast shook the island as heavy rains triggered flooding which killed at least two people, authorities said.

Footage broadcast on national television showed streets covered in deep mud and strewn with debris and uprooted trees.
