JuD chief and 26/11 mastermind Hafiz Saeed accompanied by some of the key members of JuD's cyber cell held extensive meetings with Hizb-ul-Mujahideen chief Sayeed Salahuddin and his close associates in Pakistan and held a small prayer meeting in the memory of Burhan Wani.

Wani is the Hizbul Mujahideen terrorist who was killed in Kashmir on Friday.

Pakistan has expressed shock over the killing of Hizbul Mujahideen commander Burhan Wani in an encounter in Kashmir and deplored "oppressive measures" and "excessive" force used against civilians in the latest wave of violence in the Valley.

Pakistan Prime Minister Nawaz Sharif, who has been under attack from the opposition for remaining "silent" over the killing of protesters in Kashmir, came out with a late night statement condemning the action of Indian security forces.

"The Prime Minister of Pakistan has expressed his deep shock at the killing of Kashmiri leader Burhan Wani and many other civilians by the Indian military and paramilitary forces," Sharif's office said in the statement.

The Prime Minister said it was "deplorable that excessive and unlawful force was used against the civilians" who were protesting against the killing of Wani.

"Oppressive measures such as these cannot deter the valiant people of Jammu and Kashmir from their demand of exercising their right to self-determination in accordance with the UN Security Council resolutions," he said.

Expressing concern over the detention of Kashmiri separatist leaders, Sharif said India should fulfil its human rights obligations as well as its commitments under the United Nations Security Council resolutions.

The death toll in the clashes between protesters and security forces in Kashmir mounted to 23, as normal life remained paralysed for the third day today in the Valley due to curfew-like restrictions and separatists-sponsored strike in the wake of the killing of Wani in an encounter on Friday.

Most of the separatist leaders, including Syed Ali Shah Geelani, Mirwaiz Umer Farooq and Mohammad Yasin Malik, are either in custody or under house arrest.

Pakistan People's Party (PPP) chairman Bilawal Bhutto Zardari has alleged that "Sharif-Modi friendship" was causing "irreparable damage" to the Kashmir issue.
