A fishing boat from Pakistan with four people on board went up in flames off the Gujarat coast in what appeared to be an attempt to evade investigation by the Indian Navy on New Year's Eve, the government disclosed today. So far, no survivors have been found from the vessel which set sail from near Karachi in Pakistan for what the government described as "an illicit transaction" in the Arabian Sea. Sources said the boat had ammunition that was meant to be passed onto another boat about 350 kms southwest of Porbandar in Gujarat.
