Karnal, Sept. 21 :    Karnal, Sept. 21:  Finance minister Yashwant Sinha today admitted that there was a 'feeling of uncertainty' in the economy following the terror strikes in the US and the war preparations, but felt there 'was no need to panic'. 'We are monitoring the stock exchange and foreign exchange reserves and the impact is likely to be short-term rather than long-term,' he said. The finance minister, here to attend a kisan mela organised by the Haryana government, assured that measures had been taken to check 'any slowdown in the Indian economy'. However, he added that 'more measures will be taken to correct' any damage. 'The only uncertainty,' he said, 'was the scale of US operations against Afghanistan and certain apprehensions.' But he did not specify what the 'apprehensions' were. Asked about a possible oil price jump, Sinha said petroleum minister Ram Naik had attended a meeting of his counterparts in China recently. 'Moreover, Opec has promised to keep supplies going and that is a comforting signal,' he added.
