New Delhi, Oct 4 (ANI): The tension in the Mong Kok district of Hong Kong was evident in the wake of the clashes overnight between pro-democracy protesters and their opponents. The democracy campaigners are vowing to carry on regardless. Some are accusing the pro-Beijing opposition of orchestrated harassment. Police said they'd arrested 19 people since Friday, including suspected members of the infamous Triad gangs. The pro-democracy protesters are demanding the resignation of Hong Kong's chief executive, which he's rejected. They also want China to reverse a decision to hand-pick the contenders in the 2017 election for a new chief executive, which Beijing opposes.
