Pakistan has deported more than 19,500 Afghans this month, among more than 80,000 who have left ahead of a 30 April deadline, according to the UN. Pakistan has accelerated its drive to expel undocumented Afghans and those who had temporary permission to stay, saying it can no longer cope.

Pakistan says that thousands of Afghan migrants who have applied for resettlement in third countries could face forced expulsion if they are not relocated by host countries before the end of April
