Two sisters of Pakistan’s jailed former prime minister Imran Khan, Uzma Khan and Naureen Niazi, have been released from Lahore’s Kot Lakhpat Jail, their lawyer has confirmed.

The release followed the suspension of their detention orders on Thursday. The two women had been held for several weeks ahead of a planned anti-government march in Islamabad. Their brother’s third sister, Aleema Khan, remains in custody, according to Pakistan Tehreek-e-Insaf.

Uzma Khan’s son described her 53-day detention as arbitrary. Their release came a day after Imran Khan was taken to a hospital in Islamabad for treatment of an eye condition and blood pressure.
