External Affairs Minister Sushma Swaraj has asked the Indian High Commissioner in Nigeria to take the ``abduction`` of five Indian sailors by pirates in the African nation two weeks ago, at the ``highest level``. The minister also asked Indian High Commissioner to Nigeria, Abhay Thakur, to prepare a report over the incident. ``I have seen news reports about abduction of five Indian sailors by pirates in Nigeria,`` tweeted Swaraj. The minister`s tweet comes days after media reports suggested that pirates had abducted five Indian sailors last month and took their ship MT Apecus in Bonny Outer anchorage in Nigeria. Their families also tweeted to the Indian commission in Nigeria, saying they were unable to contact the sailors.
