At least 728 people were wounded and one officer killed in overnight clashes between police and protesters, Al Jazeera reports. The Lebanese government has blamed poorly stored ammonium nitrate for the blast.

On Sunday morning, it became the second country to surpass 3 million cases, per Johns Hopkins. Only the U.S. has reported more. Bolsonaro has yet to address the milestones.
