Bharti Airtel shares sink to two-year low

Shares in Bharti Airtel lost more than 7 percent to their lowest in two years after India's top telecoms carrier posted its 10th straight quarter of profit decline as cut-throat competition squeezed margins.

Bharti's shares were down 6.4 percent at 274.80 rupees, losing about 72.15 billion rupees worth of market capitalisation in a single day. The shares touched a low of 272.40 rupees and were heading towards their biggest single-day loss since February.
