The Ansari episode reiterates what has been long believed: Pakistani ISI is hyper active in Sri Lanka.
In fact, Pakistan had appointed a former ISI officer Colonel Bashir Wali Mohammed as its high commissioner in Colombo in June 2004.
A couple of months later, the LTTE set off a three-wheeler explosion targeting him in the heart of Colombo. Seven men in his convoy were killed but Wali escaped.
It was widely believed that President Pervez Musharraf sent Col Wali to head the Pakistani mission in Colombo with a long-term plan of using Sri Lanka to infiltrate the southern parts of India.
