This week has seen the mass arrests of students at US universities. Pro-Palestinian demonstrators "have a right to dissent, not chaos", said President Joe Biden. It's also been yet another week where a breakthrough seemed possible in talks for a Gaza ceasefire. But come what may, Israel says the Rafah offensive will happen.

Meanwhile, it's been a week of warnings for world leaders not to look away from events in Sudan and the so-called invisible war. The US is warning that a massacre is imminent in El Fasher, the capital of north Darfur. Can anything be done to stop it? 

Finally, it's been the week where Spanish Prime Minister Pedro Sanchez stepped back from the brink of resigning. After a "time out to reflect" on what he called relentless personal attacks, he has vowed to carry on. But has the decision weakened or strengthened him?
