Following a series of threats by Pakistani extremist groups, including the Pakistan Taliban, India has asked Pakistan to strengthen security at the Indian embassy.
External Affairs Minister Salman Khurshid was quoted by Pakistan's Dawn newspaper as saying, "We did ask for precautionary measures in terms of protecting our diplomats in Pakistan. We sent a missive to that effect".
The report added that an Indian foreign ministry spokesman had said the demand had been made as “there was a need for extra security”.
News of Kasab's executions have sparked off angry reactions from Pakistani terror groups.
Ehsan demanded that India return Kasab’s body.
“If they don’t return his body to us or his family we will capture Indians and will not return their bodies,” he said, adding that the Taliban will try to strike Indian targets “anywhere”.
The Taliban, who are close to al-Qaida, are seen as one of the biggest security threats in Pakistan and are blamed for many of the suicide bombings across the country. They have not carried out major attacks abroad.
When news of the execution broke, The Border Security Force (BSF) also sounded a general alert along the 553-km international border between India and Pakistan on Wednesday.
Security personnel manning the international border, which has an electrified barbed wire fence inside Indian territory, were put on alert as a precautionary measure, a senior BSF official said.
