New Delhi, May 11 -- The border across the western frontier with Pakistan, especially in Jammu, will continue to be on high alertwith the maximum available boots guarding it on the ground, officials said on Saturday,soon after India and Pakistan reached an understanding to stop all military actions against each other after four days of intense armed confrontation triggered by the Pahalgam terror attack - an agreement breached by Islamabad hours later. Officials in the Border Security Force (BSF), which guards 2526.86 km of the Indo-Pak International Border and 237.2 km of Line of Control, said the force will continue to be on high alert because of mass infiltration attempts (aided by Pakistan Rangers) in the last few days at the border along Jammu sector and a history of foreign terrorists attempting to infiltrate into India from there. "There will be no decreasein the number of personnel. The Jammu sector has beenvery active in the past few days. There will be a zero-tolerance policy on infiltration," onesenior officer said requesting anonymity. Over the last 48 hours, terrorists from Pakistan-based Jaish-e-Mohammed have tried to infiltrate into India from different points along the border in the Jammu sector, officials said. On Friday night, BSF destroyed a terrorist launch pad at Looni in Sialkot district of Pakistan, along with posts and assets of Pakistan Rangers during one such attempt. Officials said the incident, second in the last 24 hours, was evidence of Pakistan Rangers helping terrorists to infiltrate into India by providing cover fire or engaging BSF personnel at the border. At RS Pura area in Jammu, also on Friday night, Pak Rangers opened fire at BSF personnel without any provocation. "Last night for the secondconsecutive night, Pakistan initiated unprovoked firing from Sialkot across the BSF posts. They were providing cover to the infiltrators," the official cited above said....
