A couple from Kashmir, accused of links with the ISIS unit from Afghanistan's Khorasan province, has been detained by the police from south Delhi, police sources said. Sources said they were planning a suicide attack in Delhi.

A senior official associated with the operation said the couple had been in touch with senior ISIS members in Afghanistan to exploit the ongoing agitation against the amended citizenship law.

The couple -- identified as Jahanjeb Sami and his wife Hina Bashir Beig – was taken into custody on Sunday morning from their home in Jamia Nagar, where the prestigious Jamia University is located. They were found to possess certain sensitive items, sources claimed. After Shaheen Bagh, Jamia has been the other big hub of the protests against the citizenship law.

Sources said Jahanjeb Sami used to work in a private company. The couple also ran a social media platform called "Indian Muslims unite", which, the police claim, worked towards mobilising support against the Citizenship (Amendment) Act (CAA) and the National Register of Citizens (NRC).

The centre has repeatedly alleged that the protests against the Citizenship Amendment Act – which figured prominently in their campaign for the Delhi assembly elections -- were a conspiracy.

Various ministers and BJP leaders have accused the Congress and other opposition parties of driving the protests.

Last month's violence in northeast Delhi, in which 53 people died, had started as clashes between the anti-CAA protesters and those supporting the law. The opposition alleges that the hate speech by a section of BJP leaders ahead of the Delhi assembly elections had contributed greatly to the violence.
