The Sunday's blast happened minutes after the ceremony.
BSF chief DK Pathak who spoke to his officers on Sunday evening to assess the situation, said the BSF had received intelligence inputs about a fortnight ago that terror groups could try to carry out a possible strike during the beating retreat ceremony.
"We were already alert in this area as we have received some inputs some time back that this area could be targeted. After the blast, we have alerted our formations along this frontier," Pathak told PTI.
He said his formations had told him that the blast occurred about 500 metres from the Wagah border retreat ceremony area on Sunday evening.
"The Pakistani Rangers initially told us that there was a cylinder blast in a tea stall but now it has emerged to be a fidayeen attack. We are not very sure about the exact reasons," he had said soon after the blast.
The trading activity between the two enemy countries is likely to remain suspended for another two days.
