[ti:] [ar:] [al:] [00:00.00]The sound of gun shots and explosions [00:02.90]echoed through the centre of Srinagar [00:05.08]after gunmen opened fire in Lal Chowk, [00:07.37]the main square in the city's commercial district. [00:10.27]After a relatively quiet period in Kashmir, [00:13.69]there have been several recent attacks - [00:15.92]four soldiers were killed in an ambush [00:18.47]by militants last week. [00:19.85]But this latest attack is even more audacious, [00:22.85]right in the heart of [00:24.32]one of the most heavily policed cities in the world. [00:27.02]Violent separatist groups, [00:29.62]some of them backed by Pakistan, [00:31.49]have taken up arms against Indian rule [00:33.89]in Kashmir for 20 years. [00:35.52]The fighting is far less intense [00:37.97]than it was in the 1990s, [00:39.80]but a political solution to Kashmir's problems remains elusive. [00:44.02]So it's been a bloody start to the New Year [00:47.23]in this highly sensitive region, [00:49.06]which has been divided between India [00:51.26]and Pakistan for decades. [00:53.09]In another sign of the complexity of the conflict, [00:56.39]four Pakistani soldiers have been killed [00:59.14]by a suicide bomber [01:00.31]in Pakistan-administered Kashmir. [01:02.71]It's a worrying development [01:04.33]for the Pakistani authorities, [01:05.96]which suggests that Taliban militants [01:08.36]may be trying to expand their area of operations.
