BANGKOK: Heavy rains have brought some of the worst floods for years to Thailand’s rural northeast where 23 people have died over the past month, officials said Wednesday. Flash floods have disrupted air travel, inundated rail tracks and swallowed farmland across the rice-farming region of Isaan, affecting more than one million Thais. Twenty-three people have died since July 5, the disaster department said in a daily update. All were swept away by the floodwaters and drowned, it said. Junta chief Prayut Chan-O-Cha flew to the hardest-hit province of Sakon Nakhon on Wednesday to inspect a reservoir that had cracked under the downpour, triggering flash floods. Ten provinces are still battling severe floods as rains continue to lash the upper part of the northeast region, according to the weather bureau.
