The suspect Amirull bin Ali was a 20-year old full-time national serviceman in the Singapore Armed Forces at the time of his arrest in February 2021. According to the Internal Security Department (ISD), Amirull developed an interest in the Israel-Palestine conflict after watching a video of Palestinian civilians being bombed by Israeli jets in 2014. His subsequent online research into the conflict led him to develop the view that Israel was oppressing the Palestinians, which led him to hate Israel and Jewish people.[1][2]
In 2015, Amirull began supporting Hamas' military wing, the Izz ad-Din al-Qassam Brigades. By 2018, he had discussed his intentions to travel to Gaza and join the al-Qassam Brigades with a foreign contact. Amirull believed that he would become a martyr if he were to die fighting the enemies of Islam in combat. Between 2018 and 2020, he also researched travel routes to Gaza. Amirull intended to join the al-Qassam Brigades after completing his national service and raising funds. For this purpose, he also trained with a replica AK-47.[1][2]
Planning and manifesto
According to the ISD's investigation, Amirull began planning his attack on Jewish worshipers at Maghain Aboth Synagogue after watching a Channel News Asia documentary on the Jewish community. He was reportedly enraged that Singaporean Jews were thriving peacefully in Singapore while the Palestinians were suffering. Amirull's plans reportedly included practising stabbing techniques with a Smith & Wesson knife, conducting at least two reconnaissance trips to the mosque between August and October 2019 to identify ambush positions, and making plans to wear a white keffiyeh to hide his identity. He planned to kill three Jewish males on the pretext that they had conducted national service in Israel and carried out alleged atrocities against Palestinians. Amirull also intended to make a short online manifesto following his attack advocating violent attacks against so-called "tyrannical regimes."[1][2]
Amirull reportedly shelved his plan in October 2019 due to the belief that he could only obtain martyrdom through death in combat. However, he revisited his plan in December 2020 after watching a TRT WorldYouTube video showing the shooting of an unarmed autistic Palestinian man named Eyad al-Hallaq by Israeli security forces. Amirull planned to attack the synagogue on Christmas Day while wearing a black ski mask. He abandoned the second attempt due to his concerns about not attaining martyrdom if he was captured by law enforcement authorities.[1][2]
Arrest, investigation and detention
In February 2021, Amirull was arrested and detained under the Internal Security Act, which allows detention without trial for a two-year period.[1][2] The ISD had been alerted to Amirull's case by the Ministry of Defence, which expressed concern that he had been radicalised by "extremist ideologies." According to the ISD, Amirull had acted alone and there was no evidence that he had tried to influence or recruit others. His family and friends were unaware of his attack plans. The Defence Ministry also confirmed that Amirull did not intend to influence anyone in his unit and that no military equipment was missing.[1]
Amirull was released on a restriction order in March 2023 after reportedly being rehabilitated by the Religious Rehabilitation Group (RRG).[3]
In addition, several representatives of the Singapore Muslim community including Mufti Dr Nazirudin Mohd Nasir, Majlis Ugama Islam Singapura (MUIS) Chief Executive Mr Esa Masood, and Head of Harmony Centre Liyana Rosli Asmara met with leading representatives of the Singapore Jewish community including Chief Rabbi Mordechai Abergel, Jewish Welfare Board Singapore President Mr Nash Benjamin and Vice-President Mr Reuben Khafi at the Maghain Aboth Synagogue to reaffirm communal ties between the two communities and condemn extremism, radicalism, and violence. Mufti Dr Naziruddin also condemned "radical and extremist ideas" within the Muslim community and emphasized the common Abrahamic heritage between Jews and Muslims.[10]
