The Chennai police tightened the security in the city where the first Test match between India and Australia is being played, after the Southern city of Hyderabad was attacked on Thursday.

Meanwhile, Australian captain Michael Clarke scored a brilliant ton under-pressure, while the new member in his team, Moises Henriques, chipped in with a valuable 68 of his own as the visitors took stumps at 316 for 7 on Day One of the first Test against India.

Australia were struggling on 153 for five at one stage in the second session, with Ravichandran Ashwin (6 for 88) leading the onslaught, before Clarke and Henriques staged a revival.

Clarke's 103 not out came off 168 balls, including 11 fours and one six. After scoring 1,595 runs in 2012, Clarke has started the new year like he ended the last.
