Mumbai, Nov 27 (ANI): Belgium Princess Astrid and Minister of State for Human Resource Development Shashi Tharoor laid wreath and paid homage to the victims of 26/11 terror attacks at the Gateway of India in Mumbai. India, on Tuesday, observed the fifth anniversary of 26/11 Mumbai carnage that shook the entire nation in 2008.
