Extended detention of Mehbooba Mufti and Omar Abdullah trigger anger against Indian government in occupied Kashmir and India.
Indian National Congress leader Priyanka Gandhi has also demanded their release.
According to Radio Pakistan, India has extended the detention of four political leaders in occupied Kashmir.
Extended detention of Mehbooba Mufti
They included former puppet chief ministers Omar Abdullah and Mehbooba Mufti.
India took the latest detention order under the draconian Public Safety Act.
That law allows detention without charges for up to two years.
However, India held them earlier under a law that allowed a maximum of six months, and their detention was about to expire.
Both the leaders, are already under detention since 5th August 2019, the day when India revoked the special status of occupied Kashmir.
National Conference, General Secretary, Ali Mohammed Sagar, was also served a PSA notice by the authorities.
