Rip currents and shifting sand channels have made three of Cox's Bazar's most popular beach zones -- Kolatoli, Sughandha and Laboni -- increasingly treacherous for tourists.

In a shocking video that went viral recently, a tourist was seen struggling against strong waves to save his son from drowning in the sea in front of a beach resort in the Kolatoli area of Cox’s Bazar.

As the sun lights up the horizon, Osman Goni starts patrolling the Cox’s Bazar sea beach. While waves crash at his feet, his eyes keep searching the distance for anyone who might need help. A team of 26 lifeguards stands ready for his order to rescue people lost in the waves.
