Security agencies probing the terrorist attack on the makeshift Ram temple in Ayodhya on Tuesday are trying to trace a call made by militants to Jammu and Kashmir [Images].

Sources said the militants had taken the mobile phone of Rehan, one of the two arrested drivers, and put their own sim card in it to make calls to their contacts.

What the Ayodhya attack signifies

Although the sim card had been destroyed by the militants before carrying out the attack, agencies were able to crack down the dialled numbers through the International Mobile Equipment Number code of Rehan's handset.

The IMEI code is a unique number which gets registered in the network that the caller is using. Without giving the call details, sources said one of the calls made to Jammu and Kashmir was being probed by the security agencies.

Meanwhile, central security agencies have formed some crack teams and dispatched them to various parts of the country, including some metropolitan cities, following leads in the case.

Police get a breakthrough

About the possibility of their route to Ayodhya, sources said it was a bit premature to talk about it as they could have entered through Nepal or from Bangladesh.

Sources said the possibility of the militants entering the state from Jammu and Kashmir was also being probed.

There were some contradictions noted in the statement of Rehan but everything would be clear only after the purpose of his visits to Saudi Arabia is confirmed, sources said.

Centre knew it was coming

Meanwhile, an official of Jammu and Kashmir police was shown the photographs of the bodies of the five slain militants. The officer failed to identify any of the militants.
