KABUL (Reuters) — Tight security ensured Afghanistan’s presidential election was held on Saturday in relative calm, though several small attacks, low turnout and complaints about the voting system heightened fears an unclear result could drive the country into further chaos.

Voter turn out was very thin, heightening fears that an unclear result could drive country into further chaos. Preliminary results are not expected before October 17 and final results not until November 7. If no candidate gets 51% of the vote, a second round will be held between the two leading candidates.

Taliban fighters attacked several polling stations across the country to try to derail the process, but intense security prevented the large-scale violence of previous polls.
