All officials posted in the Indian high commission in Islamabad have been asked to curtail unnecessary travel and venture out only with proper security guards.
"Senior diplomats posted in Pakistan have been given bullet-proof vehicles," an official said, referring to various instances of terror attacks in Pakistan.
Though there is no specific intelligence input about any threat to the Indian diplomats posted in Pakistan, additional steps have been taken for their protection.
Security of the Islamabad high commission complex has also been tightened, officials said.
Four motorcycle-borne Taliban militants yesterday shot dead a diplomat of Saudi Arabia, a staunch US ally, claiming that it was to avenge the killing of Osama bin Laden and continued drone attacks in Pakistan's volatile north-west.
