Tens of thousands of signatures have been collected across the North-East to date by the campaign - organised by the Tamil Action Committee for International Accountability Mechanism (TACIAM).
However the Sri Lankan authorities have disrupted the campaign on several occasions in both Jaffna and Trincomalee.
Signatures are being collecting signatures ahead of the United Nation Human Rights Council session later this month, where a report into mass atrocities in Sri Lanka is to be discussed.
