India's federal counter-terrorism agency arrested seven members of Held Kashmir's main separatist alliance on Monday on charges of receiving funds from militant groups it claimed were based in Pakistan to wage attacks, the first such case against the group.
The National Investigation Agency (NIA) claimed it had found cash and valuables worth millions of rupees, electronic devices and incriminating documents during raids on the seven members of All Parties Hurriyat Conference.
The Hurriyat is an umbrella group of political and religious groups fighting for Held Kashmir's secession from India.
The accused could not be reached for comment. Top leaders including Syed Ali Shah Geelani, Mirwaiz Umar Farooq and Mohammad Yasin Malik condemned the arrests as arbitrary and called for a strike on Tuesday to protests the action.
Separatist violence and street protests have increased in India-held Kashmir since last year when security forces killed a popular young separatist commander.
Separatists accuse Indian forces of rights abuses.
One of the seven arrested on charges of terror funding is Altaf Shah, a son-in-law of Geelani, who is a former chairman of the Hurriyat.
The NIA claimed the men had received funds from the Hizbul Mujahideen, a group comprising largely indigenous fighters as well as the Lashkar-e-Taiba militant group which was blamed for the 2008 attacks on Mumbai.
"Evidence collected so far clearly proves a financial trail as well as a direct link between terror activities and funding from Pakistan-based terror groups," NIA spokesman Alok Mittal claimed.
