"On May 18, 2007 a bomb blast took place in Mecca Masjid near Charminar in Hyderabad wherein 9 persons were killed and 58 others injured... These are information available in public domain, in the court records of the Special CBI Judge at Hyderabad. Certain similarities between the Samjhauta Express blasts and the Mecca Masjid blast were noticed in so far as both used batteries of 6 volts and cast iron pipes etc."
