MUMBAI, Dec 7 - Leading Indian telecoms firm Bharti Airtel sees revenue pressured in the short term amid an intense price war in the country's wireless sector, director Akhil Gupta told news channel CNBC-TV 18.

Mobile operators including Bharti Airtel, Vodafone Essar and Reliance Communications are locked in a tariff war, raising concerns about telecom firms' profitability. The price war is aimed at grabbing new users as new firms enter the market.

Norway's Telenor launched services on Thursday, becoming the 12th operator in India. Etisalat ETEL.AD, the Arab world's second-biggest carrier, is among players planning to enter the market.
