Residents of Konya Province in southern Turkey have spoken of their terror when a giant sinkhole suddenly appeared in a local field.<br /><br /> “We are very afraid (for) our lives. It is luck that no one fell into it,” said one local farmer.<br /><br /> Measuring 10 metres wide and 90 metres deep, the crater is thought to have formed in the space of 24 hours.<br /><br /> No one was injured as a result of the ground caving in.
