President Tony Tan Keng Yam and Prime Minister Lee Hsien Loong have expressed their condolences to Britain's Queen Elizabeth II and Prime Minister Theresa May respectively on an attack on Muslim worshippers on Monday as well as last Wednesday's Grenfell Tower fire.
In his letter yesterday, Dr Tan said he was appalled by the attack that targeted worshippers leaving a mosque at Finsbury Park.
"Attacks that target specific communities and could divide societies deserve our strongest condemnation. More than ever, the attack reminds us that efforts to build inter-racial and inter-religious bridges are needed," he wrote.
"On behalf of the people of Singapore, I send our deepest condolences," he added.
PM Lee, writing to Mrs May, said he was "shocked and saddened by the heinous attack" on Monday.
"Crimes inspired by Islamophobia must be condemned, just as much as extremist jihadist terrorism. We stand in solidarity with the United Kingdom to condemn this horrific act and bring its perpetrators to justice."
On the fire, Mr Lee said its scale "shocked the world, even one jaded by news of misfortunes and tragedies".
He expressed his "deepest condolences" to the families of the innocent victims of the mosque attack and fire.
