Torrential rains triggered by Typhoon Matmo have caused catastrophic flooding in northern Vietnam, resulting in at least three fatalities and leaving four individuals unaccounted for. The relentless downpour has led to widespread devastation, with thousands of homes damaged and numerous communities isolated. Rivers have overflowed their banks, exacerbating the flooding, while landslides have further complicated rescue efforts in the affected provinces, including Cao Bang, Thanh Hoa, and Thai Nguyen.
