Tidal waves generated under the influence of Tropical Cyclone Kyarr, wreaked havoc in a coastal settlement near Gwadar, on Wednesday.The Arabian Sea waves surged and submerged several houses and mud huts in coastal settlement of Gunnus. The high waves surged to cause collapse of walls of the huts leaving the people to fight the natural calamity. The residents of the settlement fearing surge in tidal waves in the night time were forced to take refuge at nearby hill.Local people have demanded the government to take substantial steps for protection of the settlement from intrusion of the seawater. The local administration has provided tents for the affected people and heavy machinery also reported to be deployed for construction of a protective dyke along the settlement.Earlier, around 20 villages of Keti Bandar, Joho, Kharo Chhan, Garho and Bohara along the coastal area of Thatta district suffered the sea intrusion, sources said.
