New Delhi: Unidentified hackers have posted Indian national anthem and Independence Day greetings on a Pakistani government website on Thursday.

The incidents comes almost four months after a Pro-Pakistan group hacked the official websites of four prominent Indian institutes—Indian Institute of Technology Delhi (IIT Delhi), IIT Varanasi, Aligarh Muslim University (AMU) and Delhi University (DU)— and some lesser known institutions several times on Tuesday.

While all four educational institutes restored their websites initially, the hackers brought then down again and posted the pro-Pakistan, anti-India messages on these websites.

The hacker group code named “Pakistan Haxors Crew " wrote abuses about Indian government and the Indian Armed forces on the landing pages of the websites. The hacker group said: “Nothing deleted or stolen. Just here to deliver my message to Indians."

The Pakistan Haxors Crew also said the hack was in response to an Indian hacker hacking that country’s railways website.
