Indian security agencies are on high alert ahead of Independence Day on 15 August, following credible intelligence inputs warning that elements backed by Pakistan's Inter-Services Intelligence (ISI) could attempt a major strike — either along border areas or inside the country. The threat assessment, shared by officials in New Delhi, points to a deliberate ISI strategy timed to exploit security focus on the national celebrations.

The Intelligence Warning

An Intelligence Bureau official said the ISI believes that security agencies — particularly in Delhi and Jammu and Kashmir — will be heavily occupied with Independence Day arrangements, creating a window for action.

'The ISI is trying to exploit this and will attempt something major either on Independence Day or ahead of it,' the official warned.

According to officials, the ISI is also under domestic pressure, with unrest in Pakistan-occupied Kashmir (PoK) and Balochistan putting the Pakistani establishment on the back foot. A high-profile strike on India's Independence Day, officials say, would serve as a significant diversion.

Infiltration and Two-Tier City Threats

Intelligence inputs indicate that the ISI's first line of action would be to push terrorists across the Jammu and Kashmir border. Infiltration attempts through the Bangladesh border are also being anticipated.

Notably, officials flagged that the ISI is reportedly targeting two-tier cities — locations where security infrastructure is generally thinner than in metros and major urban centres. This represents a tactical shift from the agency's traditional focus areas.

Officials also cautioned that the ISI may deliberately plant false alarms in Delhi or Kashmir to divert agency attention while planning an actual strike elsewhere. 'Many such intelligence inputs are generally not actionable in nature. This is a deliberate strategy to divert attention,' an official said.

BSF Launches Operation Alert

At the western border with Pakistan, the Border Security Force (BSF) has launched Operation Alert, which began on 10 August and runs through 17 August. All senior BSF officers are participating in the exercise, which follows specific information about a possible ISI misadventure.

'There is also credible information about possible infiltration and smuggling attempts. Surveillance and patrolling have been increased significantly in these areas,' an official said. A large force has been deployed to monitor every activity along the border during this period.

40 New Intelligence Units on Bangladesh Border

On the eastern front, the Centre has decided to establish nearly 40 Subsidiary Intelligence Bureau (SIB) units across bordering districts in West Bengal to bolster surveillance along the Bangladesh border.

Officials described this as one of the largest expansions of the Intelligence Bureau's field structure. The move is aimed at establishing a permanent operational presence in an area where smuggling, infiltration, and extremist activity are regularly reported.

'Securing the border requires constant surveillance and continuous intelligence gathering. Given the persistent nature of these attempts, it is crucial to have real-time intelligence to detect and thwart any nefarious activity,' the official said.

Security Focus: Punjab, J&K, and Delhi

Security agencies are currently maintaining heightened vigilance across Punjab, Jammu and Kashmir, and Delhi — areas that have historically been primary targets of the ISI. Officials acknowledged that while an attack in any of these locations would carry symbolic weight, the tight security arrangements in place make execution significantly more difficult for the agency.

With Independence Day days away, the security establishment faces the dual challenge of managing a high-profile national event while neutralising a multi-pronged threat that spans both western and eastern borders.
