Intelligence agencies have sounded a high alert in New Delhi ahead of the Independence Day celebrations, with sources saying officials suspect that explosives and weapons have been smuggled through Pakistan using drones.

This information was received during the interrogation of terrorists arrested recently in Punjab.

Sources said that the Improvised Explosive Device (IED) has been smuggled into the country through the India-Pakistan border.

The police also recently recovered 2,251 live cartridges, which were to be supplied to Lucknow in Uttar Pradesh.

The police have not yet ruled out a terrorist angle in the case.

In view of security, about 1,000 cameras will be used.

These cameras will be installed by the North, Central and New Delhi district units of the city police.

These cameras will also help in surveillance.

Special watch will be kept on the VVIP route leading to the Red Fort.

Intelligence agencies have asked Delhi Police to tighten screening during the Independence Day program at the Red Fort, where PM Modi will deliver a speech.

According to the intelligence agency, weapons, such as AK-47, have been transported through Pakistan to some places in India through drones.

Apart from this, inputs of Lone Wolf Attack have also been given by security agencies to Delhi Police. 

According to the IB, anyone can attack in the crowd.

In such a situation, it has been asked to keep the screening and checking very strong. 

The intelligence agency has said that someone can attack by putting some suspicious items in crutches, so the screening should be very strong. 

IB has given an alert to attack through kites.

Along with this, instructions have been given to completely ban and keep an eye on kites around the Red Fort.

Recently, terrorists arrested in Punjab and different states told during interrogation that terrorist organizations have sent a lot of IEDs to India through drones.
