Kate Adie introduces stories from the US, Portugal, the South China Sea, Argentina and Antarctica. University campuses across the US have been gripped by protests over the war in Gaza, with students demanding their schools divest from Israeli interests. Nomia Iqbal considers the ramifications of the protests for Joe Biden, who will need the youth vote on his side if he is to win re-election in November. In the days after the Hamas attacks, some 200,000 Israelis were evacuated from Israel's border regions with Gaza and Lebanon, and moved into temporary accommodation. While some have since decided to return home, others have decided to seek safety further afield, as Mark Lowen discovered in Lisbon. Confrontations between the Philippines and China are on the rise in the South China Sea, as the countries clash over a territorial dispute. Jonathan Head saw this maritime feud up close, while on board a Filipino coastguard ship as it came into contact with a Chinese patrol. Argentina's President Javier Milei was elected last year on a manifesto of slashing public spending. Yet, with inflation at 300 per cent, prices are still spiralling, and another national strike is on the horizon. Mimi Swaby discovers it’s a crisis that continues to affect all corners of this vast country. And we’re amid the icebergs and marine life of Antarctica, as Janie Hampton recounts her voyage to trace her family connections to the continent - revealing how the downfall of the Soviet Union led to the cut-price sale of a British research base.
