Note the FAC title on its tail, this is one of those for Colombia.
About Sri Lanka, you mean the C.2/TC.2, they weren't upgraded. They were augmented by more C.2s and four C.7s in 2001, two of the C.7s were lost in LTTE attacks. Also, most up-to-date report I've got on it (last month's AFM actually) said the C.7 were grounded because of lack of spare parts for the more sophiscated avionics.
