On Friday, Pakistan's Minister of Communications and Postal services announced that the bus service stood suspended.
"In line with the decisions of NSC Pak-India bus service is suspended," Saeed wrote on Twitter.
Yesterday, Pakistan Minister of Railways Sheikh Rasheed Ahmad also announced the suspension of two trains -- Samjhauta Express and Thar Express -- between the two neighbouring countries.
The decision to suspend the two trains, as well as the bus service is in line with Islamabad's other moves to remonstrate, including suspending bilateral trade and downgrading of diplomatic relations.
Calling its steps in Jammu and Kashmir an "entirely internal" affair, India has rejected Pakistan's unilateral move to downgrade diplomatic ties and asked Islamabad to review them so that normal channels for diplomatic communications are preserved.
