The Taliban have captured eight more districts of north-eastern Badakhshan in the past twenty hours.
Meanwhile three hundred Taliban were killed in fighting with government forces in several provinces of the country.
Afghan Ministry of Defence said scores were killed in air strikes including a pre-dawn assault today, in the southern province of Helmand, where the Taliban and government troops are engaged in fierce battle.
Meanwhile, the Taliban rejected the government's claims.
On the other hand, the United States has announced it would finish withdrawing its troops from the country by the end of August.
