The tweets from Amrullah Saleh were in response to claims made by US Secretary of State Antonio Blinken in a recent interview that Ghani was responsible for the collapse of the previous Afghan government.
Based on the historic responsibility of the Afghan government and after consulting with the elders of the country, the government in exile has been announced, the statement said.
Ahmadullah Wasiq, deputy head of the Taliban Cultural Commission, denied reports in an interview to Afghan daily Al-Itteza after a video went viral on social media which showed two suitcases stuffed with cash and gold bricks.
Amrullah Saleh appealed to the UN, Red Cross and Red Crescent Movements, NGOs and other charity organisations to respond to the humanitarian crisis in Panjshir and other areas.
