The Civil Defense used high-powered pumps to drain a lake where an Asian man drowned on Monday, finally locating and recovering his body 17 hours after the incident was reported. The deceased had been swimming at the site in Al-Muzahamiya with a work colleague when he found himself in difficulties caused by thick mud and clay on the floor of the lake. The spokesman for the Civil Defense here appealed to the public to refrain from swimming at such sites, reiterating calls from counterparts in Dhulum on Monday prompted by the death of a 19-year-old man in similar circumstances.
