JORHAT: Amid the stand-off with Mizoram in Cachar on Monday that cost five cops their lives, Assam on Tuesday beefed up security along another potential border flashpoint — its long-disputed boundary with Nagaland in Jorhat district, reports Anup Dutta. “Security forces have been put on high alert at all vulnerable points along the inter-state boundary to pre-empt any untoward incident,” said a senior police officer in Jorhat. “We have received strict instructions to ensure law and order in the disputed areas. Besides anti-social elements, members of some rebel groups are active along the border.”
