The Taliban said on Monday the condition of the American hostage they are holding has deteriorated and that he is in poor health. 

In a statement, Taliban Spokesman Zabihullah Mujahid noted that the American teacher "Kevin King" is suffering from heart and kidney problems, and often loses consciousness, ABC news reported.

The Taliban will hold the US government responsible if anything happens to King, the statement added.

In August 2016, King and his Australian colleague Timothy Weekes were abducted outside the American University of Afghanistan in Kabul, where they worked as teachers.

Since then, the Taliban have released two videos of the captives to deliver a message on behalf of their abductors, asking President Donald Trump to offer a prisoner exchange to secure their freedom.
