India and Israel also signed an agreement, upgrading their bilateral relations to a 'strategic partnership'. During the trip, Prime Minister Modi also addressed the Indian diaspora in Israel in a highly televised event in Tel Aviv. In illustrating an Indian welcome to the Indian diaspora from its homeland, he announced Overseas Citizenship of India cards for Jews of Indian origin who had completed their compulsory military service in the Israel Defense Force and also pledged the construction of a major Indian cultural centre in Tel Aviv. Modi also visited the northern Israeli city of Haifa, where he paid homage to the Indian soldiers of the Indian Army who had fallen to save Jewish land in the Battle of Haifa, and unveiled a special plaque commemorating the steadfast military leadership of Major Dalpat Singh who liberated the ancient city from the powerful Ottoman Empire.
