Less than a fortnight before India and Pakistan's Independence Day celebrations, unidentified hackers took over the Pakistan government's official website and replaced its contents with India's national anthem and August 15 Independence Day greetings, according to several media reports.

The hacked website was down for a little while before coming back up a little before 4pm and at the time of this report it is still inaccessible.

The matter came to light after screenshots of the hacked website were shared on social media sites.

This incident comes almost four months after a pro-Pakistan group hacked the websites of four prominent Indian institutes — Indian Institute of Technology Delhi, IIT Varanasi, Aligarh Muslim University and Delhi University.

This is not the first time that Pakistan government's website has been hacked.

Pakistan celebrates its Independence Day on August 14, while India marks its freedom from the British the following day.
