Dozens of Palestinians were killed while awaiting aid in two separate Israeli attacks in the Gaza Strip on Thursday, Gaza's Hamas-run Health Ministry has said.

In the first incident, Palestinian health officials in the Hamas-ruled strip said eight people were killed in an air strike on an aid distribution center in Al-Nuseirat camp in the central Gaza Strip.

Later, at least 20 people were killed and more than 155 were wounded by Israeli gunfire at a crowd awaiting aid trucks at a northern Gaza roundabout, Gaza's Health Ministry said.
