[BBC] Something mysterious, queasily spectacular, and extremely dangerous is happening in Cape Town.In the space of a few months, half of the city's entire stock of more than 80 suburban trains has been set on fire and taken out of action.
That has prompted chaos and frustration for thousands of commuters, and deep unease for officials unsure if the arsonists are petty criminals, sophisticated gangs, or maybe even political forces seeking to discredit their rivals.
Viral videos have shown a series of burning carriages - billowing with black smoke while electric cables crack and fizzle overhead - screeching to a gentle halt in different train stations in the South African port city, as commuters rush to escape the fires.
So far, no-one has been hurt.
