"Ct/GD Ranjit Yadav displayed conspicuous bravery, high degree of dedication & devotion to duty during the exchange of fire when suspected Kuki miscreants resorted to indiscriminate & heavy volume of firing towards BSF troops. Prahari Parivaar stands in solidarity with the bereaved family." Meanwhile, a defence release said that multiple incidents of violence, arson and firing in Sugnu and Serou in the past 48 hours necessitated the redeployment of additional troops. "Extensive area domination operations by the Assam Rifles, BSF and Manipur Police were undertaken in the Sugnu and Serou areas. Intermittent firing between security forces and the insurgents took place throughout the night. Security forces effectively retaliated to the fire," it said. The troops were tasked to beef up ongoing extensive area domination operations, ambushes and measures to prevent violence. Security frces took adequate measures to prevent insurgents from 'breaking contact' and running away to nearby areas. Sugnu was comparatively peaceful even after the break out of the ethnic clashes in Manipur on Monday 3. However on June 2, heavily armed militants set fire to the house of former minister and Congress MLA K. Ranjit, as well as many other residences. All houses at Serou have been burnt completely and people were taking refuge at Sugnu. Following the burning of houses, people of the area started attacking the camp of a Kuki militant group under Suspension of Operations (SoO) agreement. /IANS
