NEW DELHI (Online) - In yet another public humiliation, Indian Navys three-page PR publication in a popular national newspaper carried another blunder. The title 'Guardians of the Sea showed a Pakistani J-17 Thunder Jet fighter, Indian media reported on Monday. This mistake was carried forward in the next two pages also. The Indians havent learnt from their mistakes so far, report said. It further stated that Indian Navy got embroiled in a controversy on Sunday when, in an advertisement released on the occasion of Navy Day (December 4), a Pakistani fighter jet was featured in a PR publication instead of an Indian aircraft. The JF-17 jet shown in the advertisement was made by China and Pakistan as a joint venture. So far, there has been no official reaction from Indian Navy on the issue. Indian Navy commemorates the day when, in 1971, its naval missile boats attacked Karachi harbour.
