Watch | Heavy rains paralyse Chennai, flights, train services suspended

These visuals from rains in Chennai showcase the worst ever flood situation in Tamil Nadu.

Flooded runways forced authorities to suspend all flights till 6am in the rain-ravaged capital of Tamil Nadu. Meanwhile, trains packed with passengers were rendered immobile on tracks overflowing with water. Cars, trucks and buses could not enter Chennai, or go out of it, as most of its main roads were blocked by several feet of water. Several roads were closed after big sink holes were found. Normal life has been completely disrupted and the non-stop torrential rain is set to last for the next three days, at least.
