While it is too early to assess as to who might have been responsible for the attack and why, one has to recall past instances of contacts of the Liberation Tigers of Tamil Eelam with the Harkat ul Mujahideen (known as the Harkat ul Ansar before 1997), a member of the International Islamic Front of the Al Qaeda and the role played by the commercial ships of the LTTE in the 1990s in facilitating heroin smuggling from the Afghanistan-Pakistan region.
