Ethnic tensions had risen prior to the April election when UMNO secretary-general Syed Jaafar Albar utilised the Utusan Melayu to accuse Lee of evicting Malays from their homes in March 1964. Lee explained personally to the affected neighbourhoods that the scheme was part of an urban renewal plan and that eviction notices had been sent to everyone irrespective of race. Albar responded by warning Lee to not "treat the sons of the soil as step-children" and led calls for the deaths of Lee and Social Affairs Minister Othman bin Wok on 12 July. On 21 July, the 1964 race riots in Singapore erupted during a celebration of Prophet Muhammad's birthday, lasting four days, killing 22 and injuring 461. Further riots occurred in late-August and early-September resulting in communities self-segregating from each other, which Lee characterised as "terribly disheartening" and against "everything we had believed in and worked for". Lee never forgot the Malay PAP leaders who stood against UMNO during the turmoil and as late as 1998, paid tribute to them for Singapore's survival.
