As Cyclone Fani moves north-northeast along India's east coast, Bangladesh is bracing itself for the storm, which has left two people dead in the Indian state of Odisha.

In Bangladesh, 400,000 people on the coast have been evacuated as of Friday afternoon, said Enamur Rahman, the State Minister for Disaster Management and Relief. Authorities aim to have 2.1 million evacuated by evening.

More than 4,000 cyclone shelters have been set up for evacuees, stocked with drinking water, dry food, and medicine. 56,000 officials have been deployed for evacuation and rescue operations.

Aid agencies are also concerned for hundreds of thousands of Rohingya refugees who fled ethnic violence in Myanmar and are living in refugee camps in Bangladesh near the coast.

UNHCR, the UN refugee agency, tweeted on Wednesday that it had prepared 135 emergency response containers with sleeping mats, blankets, rope, and other resources. Key among the items are emergency tents which can be "rapidly deployed" if families' makeshift shelters collapse during the storm.
