SIALKOT - The owners of all the 300 bricks kilns in district have announced to lock-up their bricks kiln from July 1, in protest against the levy of general sales tax (GST) on the sale of bricks. It is to be noted that the supply of bricks has already been suspended for the last four days in district. Bricks Kilns Owners Association Sialkot District President Khawaja Zafar Iqbal announced this while addressing a press conference here on Tuesday. He termed the imposition of GST on bricks as great pity and injustice, saying that this levied GST would enhance the cost of the bricks, besides, rendering thousands of labourers and workers jobless. Meanwhile, hundreds of the bricks kilns owners and labourers took out a protest rally in Sialkot during the light rainy weather. The rally began from congested China Chowk and ended at Allama Iqbal Chowk after passing through all the main city roads. The protesters were holding banners and placards and chanting anti-government slogans, demanding immediate withdrawal of the GST.
