India on Tuesday advised its citizens to avoid an annual Sikh pilgrimage to Pakistan, citing deteriorating security in the neighbouring country. 'The government of India is of the view that it is not advisable for Indian pilgrims to visit Pakistan in the prevailing situation when frequent terrorist attacks are taking place in Punjab province,' the home ministry said. 'The government advises all Indian citizens to avoid undertaking any visit to Pakistan for this purpose, till the security situation in Pakistan improves,' it said in a statement. Some 4,000 devotees are scheduled to attend the death anniversary of Sikhism's founder Guru Nanak Dev on Monday in the Pakistani city of Lahore, the Press Trust of India said, quoting event organisers.
