About that incident
It's really very shocking. Actually the programme is organised by the architecture students of different level/ terms of Khulna university and they took guests with them.
I have a friend there and he was also in the tour. But he survived death allah'r rohmote.
He was also taked away by the wave but rescued by fellow students.
There were no teachers with them. It's just a student's approach and they didn't take any security pre-cautions.
We don't have coast guards or likeminded ppls engaged in our main coastline and this was another sad incident which can easily avoided.
May their departed soul rest in piece.
I've heard that 2 may be 3 of the students stucked into quicksand and wave just drowned them and choaked into death.
