The Air India flight landed at Changi Airport after being escorted by air force F-15SG jets, in what was the third threat to the national carrier in recent days

Singapore’s air force mobilised two fighter jets late on Tuesday in response to a bomb threat on an Air India Express flight bound for the city-state, its defence minister said.

Two Singapore air force F-15SG jets scrambled and escorted Air India flight AXB684 away from populated areas after the airline received an email that there was a bomb on board its plane, Ng Eng Hen said in a Facebook post.
