President Tony Tan Keng Yam joined about 400 congregants at an iftar, or breaking of fast, session at Yusof Ishak Mosque (Masjid Yusof Ishak) yesterday.

It was his first visit to the recently opened mosque in Woodlands, which is named after Singapore's first president.

He was accompanied by (from far right) Minister-in-charge of Muslim Affairs Yaacob Ibrahim; the widow of president Yusof Ishak, Puan Noor Aishah; and Islamic Religious Council of Singapore president Mohammad Alami Musa.

Speaking to reporters at the event, President Tan stressed the need for Singapore to uphold its multiracial and multi-religious harmony in the light of recent terror attacks around the world.
