Singapore's former Prime Minister Lee Kuan Yew's condition has "worsened due to an infection" and he is on antibiotics, according to a statement by Singapore's Prime Minister's Office on Tuesday.

新加坡总理办公室周二发布的一份声明称，前总理李光耀病情“因感染而加重”，目前他正在接受抗生素治疗。

The PMO statement said doctors are closely monitoring his condition.

Lee has been in hospital since Feb. 5, when he was admitted for severe pneumonia.

The PMO said in the statement released earlier that Lee remained sedated and on mechanical ventilation in the ICU at Singapore General Hospital.

He was continuing with his antibiotics.
