This week has seen another changing of the guard in the French government. Former defence minister Sébastien Lecornu has assumed the role of French prime minister. In the US, conservative activist Charlie Kirk, a close ally of President Donald Trump, has been shot dead by a sniper as he spoke to students at Utah Valley University. And an unprecedented Israeli attack on Hamas's negotiating team in Doha has left international observers asking if Israel has crossed a red line in its ongoing war.
