In a joint statement, unity minister Aaron Ago Dagang and religious affairs minister Na’im Mokhtar said the religious harmony committee would discuss the situation and take immediate action to maintain harmony.

Both ministers issued a stern warning to all to refrain from stirring up past racial polemics, which could lead to social tensions among Malaysia’s multiethnic, multireligious, and multicultural population.

They said in a statement that no one should provoke religious sensitivities and that everyone should adhere to the Federal Constitution.

On Sunday, a petrol bomb was thrown at a KK Mart outlet in Kuching, the third such attack on the convenience store chain in a week.

Kuching police chief Ahsmon Bajah said the attack was reported by a 25-year-old man who worked at the outlet in Jalan Satok.

KK Mart outlets in Bidor, Perak, and in Kuantan, Pahang, were also attacked with petrol bombs last week, leading to the sultans of both states issuing strongly worded statements.

The petrol bomb thrown at the shop in Bidor on March 26 failed to explode, while the attack in Kuantan on March 29 set several items on fire, but the flames were immediately put out by KK Mart workers.

KK Mart has been mired in controversy since March 13 after socks with the word “Allah” were discovered at its Bandar Sunway outlet, sparking calls by Umno Youth for a nationwide boycott of the chain.
