Good morning.

Eight people have been injured in an attack in Boulder, Colorado, after a man is alleged to have thrown an incendiary device into a crowd and yelled: “Free Palestine”. The FBI is treating the incident as an “act of terrorism”.

Who are the victims? Six of the people wounded were between the ages of 67 and 88, police said, and their injuries ranged from minor to “very serious”. When police responded, they found people with injuries consistent with burns. Four were taken to a local hospital, while two had to be airlifted to a hospital in Aurora.

What has Russia been doing? It has also been launching attacks ahead of the second round of direct talks between Kyiv and Moscow in Turkey on Monday. Russian shelling and air attacks killed five people outside Zaporizhzhia, south-east Ukraine, while at least six others were injured in a drone attack in Sumy, regional officials said.
