The occupants of the two explosives-laden boats from Karachi which had entered the Indian waters off Gujarat had plans to carry out a 26/11 type attack in Porbandar city, the officials probing the incident said.

The National Technical Research Organization (NTRO), which had recorded the radio communication between the two boats, revealed that the terrorists had plans to repeat 26/11 carnage in Porbandar.

According to the transcripts of radio communication between NTRO and the Indian Coast Guard accessed by Aaj Tak show that both the vessels were in regular contact with Pakistan's maritime agency and the army.

After the NTRO alerted the coast guard, an intensive hunt was launched for the vessels. But around 5 a.m. on December 31, one of the boats exploded when the coast guard tried to intercept it. It is believed that the crew of the boat may have set off the blast to destroy any evidence.

There is, however, so far no information on the occupants of the boat.

A conversation recorded from the second boat said the boat, which was destroyed, has done its work and has handed over the things to the other boat, but it had to return back as it developed a hole in it.

The coast guard is still in search of the second boat.

The probe so far has revealed that the boat which exploded had explosives on board, evident from the bright light emitted after the blast.

Meanwhile, heavy shelling by Pakistani forces on the border in Jammu and Kashmir continued for the fourth day on Saturday.

A woman was killed and eight other civilians were injured as Pakistani troops targeted villages and 13 border outposts with heavy mortar shelling in Kathua and Samba districts of the state.

The fresh ceasefire violations have triggered migration from border villages and over 1,000 people have been evacuated from hamlets in Samba and Kathua district, officials said.

The latest round of firing by Pakistan which started on New Year eve has left two persons dead, including a BSF jawan, and nine injured while five Pakistani Rangers have been killed in retaliatory firing by India.

It comes barely two months after the last major escalation that left 13 people dead and displaced 32,000 border residents.
