Nigeria Hajj row over unescorted women
Nigeria has suspended all Hajj flights to Saudi Arabia following the deportation of more than 170 Nigerian women who had arrived in the country without male escorts.
More than 1,000 Nigerian women intending to make the Muslim pilgrimage to Mecca have been detained by Saudi authorities since Sunday.
There has been an understanding in the past that Nigerian women are exempt from travelling with a male relative - a requirement for women on the Hajj.
Two women among those who were deported spoke to the BBC just after they arrived back in Nigeria.
