Mocha is the most powerful cyclone to hit Bangladesh since 2007 and is likely to affect more than 2 million people directly in its path.
EDnews informs via DW that cyclone Mocha hit the coasts of Bangladesh and Myanmar on Sunday.
It is the most powerful cyclone to hit the region in more than 15 years.
Packing winds of up to 210 kilometers per hour (130 miles), equivalent to a category 5 hurricane, the cyclone forced authorities to evacuate hundreds of thousands of people to shelters.
