• India planning similar measures with Jhelum river
• Pakistan bans Indian flag carriers at all ports
• Modi meets Indian Air Chief Marshal 

Days after placing the Indus Waters Treaty into abeyance to punish Pakistan over the Pahalgam terror attack, India has curtailed the flow of water through the Baglihar dam on the Chenab river and is planning similar measures at the Kishanganga dam on the Jhelum River, PTI reported, citing a source.

India has taken several punitive measures against Pakistan following the cold-blooded killings of 26 people – mostly tourists – in Jammu and Kashmir's Pahalgam on April 22, including downgrading diplomatic ties, banning Pakistani ships from Indian ports and stopping imports.

Pakistan had objected to India's suspension of the Indus Waters Treaty, declaring that any attempt to stop waters flowing into the country would be deemed an act of war.

The source familiar with the matter told the news agency these hydroelectric dams – Baglihar in Ramban in Jammu and Kishanganga in north Kashmir – offer India the ability to regulate the timing of water releases, reports Hindustan Times online.

The Baglihar dam has been a longstanding point of contention between the two neighbours, with Pakistan having sought World Bank arbitration in the past. The Kishanganga dam has faced legal and diplomatic scrutiny, especially regarding its impact on the Neelum River, a tributary of the Jhelum.

On Saturday, Pakistan banned Indian flag carriers from using its ports hours after New Delhi announced a similar measure as a fresh punitive step against the neighbouring country for its role in the April 22 attack.

"In view of the recent development of maritime situation with neighbouring country, Pakistan in order to safeguard maritime sovereignty, economic interest and national security enforces following measures with immediate effect: Indian flag carriers shall not be allowed to visit any Pakistani port, Pakistani flag carriers shall not visit any Indian port (and) any exemption or dispensation shall be examined and decided on case to case basis," the Dawn reported, quoting an order by Pakistan's Ministry of Maritime Affairs' Ports and Shipping Wing.

Meanwhile, Chief of Indian Air Force Air Chief Marshal A P Singh yesterday met Indian Prime Minister Narendra Modi and is understood to have discussed the security situation arising out of the escalating tensions between India and Pakistan.

Singh's meeting came a day after Navy Chief Admiral Dinesh K Tripathi met the Prime Minister on Saturday and briefed him on the overall situation in the critical sea lanes in the Arabian Sea.

India's Border Security Force (BSF) has taken into custody a Pakistani Ranger from along the international border in Rajasthan on Saturday. The development follows the detention of BSF constable Purnam Kumar Sahu by the Pakistan Rangers. Sahu was apprehended on April 23 after he inadvertently crossed the international border while escorting farmers along the Ferozepur sector in Punjab.

The apprehended Pakistani Ranger, whose identity is yet to be disclosed, is currently in the custody of the BSF's Rajasthan Frontier.
