Siliguri, Nov 19 (ANI): Troops of India's paramilitary, Border Security Force (BSF) were put on high alert at the Bangladesh border with intelligence agencies predicting an increase in infiltration due to the growing political instability in the delta nation. Inspector General of BSF's North Bengal Frontier, S. K. Sood told a journalist in Siliguri that troops have been told to cover all gap areas along the border to counter any infiltration bid. The clash of ideologies could plunge Bangladesh into a cycle of violence as the two main political parties - ruling Awami League led by Prime Minister Sheikh Hasina and Bangladesh National Party (BNP) headed by Begum Khaleda Zia, locked in decades of mutual distrust, exploit the tension between secularists and Islamists ahead of elections. In the recent months, Bangladesh has been hit by a wave of violent protests over war crimes convictions, presenting the government with a security and credibility challenge ahead of polls early next year.
