Hong Kong leader Carrie Lam apologized on Monday after police hit a major mosque with a water cannon as they battled protesters during another day of political unrest in the Asian financial hub.
Lam visited the mosque before she was due to head to Japan to attend Emperor Naruhito's enthronement ceremony in Tokyo, and as the city cleaned up the mess from violent protests the night before, the latest in five months of political turmoil.
In Sunday's clashes, police used water cannon trucks to disperse protesters, spraying jets of blue dye into the crowds.
