Below given is the news paper report of TOI

                    A palm leaf manuscript discovered from Harappan site in Afghanistan has strengthened the belief of existence of a proto Brahmi script, which was used by Indus Valley people. This discussion was raised by Dr DP Sharma, Harappan archaeologist and director, Bharat Kala Bhawan, Banaras Hindu University (BHU) in the International Conference on Harappan Archaeology held recently in Chandigarh.

                      According to Sharma, who has carried out research works on the palm leaf manuscript with Archaeological Survey of India (ASI) for last five years, the palm leaf has Harappan as well as Kohi script engraved. "Kohi symbols and letters have an affinity with the Harappan script and hence can be very significant in the decipherment of Harappan scripts. At the same time the palm leave manuscript has seven lines, which is the longest script recovered from any Harappan site. So far the scripts or the signs of Indus Valley script engraved on tablets, seals, potteries and other objects had not more than 18 letters or pictures," informed Sharma.
