Puducherry's iconic pier at the Rock beach collapsed partially on Saturday night due to high waves as a result of deep depression over the Bay of Bengal.

Meanwhile, the depression over southwest Bay of Bengal moved nearly southwestwards with a speed of about 07 kmph during the past six hours and lay centred over the same region, about 310 km north-northeast of Trincomalee (Sri Lanka), 260 km east-northeast of Nagappattinam, 270 km east-southeast of Puducherry, said the Indian Meteorological Department on Sunday.
