Anglicans in the Diocese of Seychelles have appealed for prayer and financial support after being hit by flooding.

The Primate and Bishop of Mauritius, Archbishop Ian Ernest, took to writing to members of the Anglican Communion as the crisis has gone largely unreported in the global media.

The heavy rains have caused widespread flooding and triggered landslides on the main island of Mahe, where the majority of the Seychelles' 85,000 inhabitants live.

A state of emergency was declared on Monday and the government has set up a taskforce to address the situation.

In his letter, the Archbishop raised awareness of the devastation caused by the recent extreme weather and asked for assistance.

Although there has been no loss of life, he said the country and the diocese had suffered "heavy losses" in the floods, with many church buildings being destroyed.

"I as Archbishop of the Province, therefore, call on your solidarity to sustain the diocese of Seychelles as it strives to recover the loss suffered in the last few days," he said.

"Your prayerful support and gesture of generosity will be greatly appreciated."
