Some 200 people have been killed after Cyclone Aila swept across eastern India and Bangladesh, flooding villages and leaving millions of people marooned or forced to live in shelters.

The toll in Bangladesh rose to more than 130 following the recovery of dozens of bodies on Tuesday, local media reported.

And in India's West Bengal state, there were reports of 64 deaths, according to Ashok Mohan Chakraborty, the state chief secretary.

Cyclone Aila hit the region on Monday, triggering tidal surges and floods, and officials in both countries said they feared the toll would continue to rise as rescue teams continued their search.

'Millions affected'

Officials in Bangladesh moved about 500,000 people to temporary shelters after they fled their homes to escape huge tidal waves churned by winds of up to 120kph.

"Millions of people have been affected by the cyclone, with half a million in shelters and another half a million forced from their homes or were marooned," a disaster control official told the Reuters news agency in Dhaka, the Bangladeshi capital.

Heavy rain triggered by the storm also raised river levels and burst mud embankments in the Sundarbans delta in West Bengal.

The worst affected area in Bangladesh was the Satkhira district, near the port of Mongla, where a local official said 31 bodies were found in one village.

"The situation here is alarming," Mohammad Abdus Samad, deputy commissioner of Satkhira, told Reuters.

Meanwhile, it remained difficult to assess how the storm and flooding had affected the tiger population in the region as water levels were too high for ecologists and forest officials to survey the area, Mrinal Chatterjee, the project director of the Institute of Nature Lovers and Climbers, an environmental group, said.

Al Jazeera's meteorologist Steff Gaulter, said: "At its peak it was giving sustained winds of around 90kph and gusts of up to 150kph, but it's over land now … and has been for over 24 hours now, so there's not much left to it now except some heavy showers."

About 250 tigers are estimated to live in the Indian side of the Sundarbans reserve, with another 250 thought to reside in the Bangladeshi side of the conservation area.
