The leaders of NATO member states are meeting in Ankara, ostensibly to discuss increasing defence investment and long-term military support for Ukraine. But the war on Iran is hanging over the gathering. One of the most significant is freedom of navigation in the Strait of Hormuz - the vital waterway that Iran effectively closed for months. Ahead of the NATO summit, the US had called on European allies to help it secure the strait. They refused, with some arguing that the war has nothing to do the bloc. So, could the divide between the US and its allies be bridged in Ankara?

Ukrainian attacks have disrupted one-third of Russia's oil refining capacity, according to independent energy analysts. The resulting fuel shortage has forced Moscow to extend petrol export bans and restrict sales in more than 40 regions and Crimea. President Vladimir Putin says the strikes are not critical and insists the war will continue until his goals are met. Russia is continuing its attacks on Ukraine, including a huge strike on Kyiv on Thursday. So, can economic pressure on Russia bring an end to the war - which has stretched into a fifth year?

Beijing's new ethnic unity law strengthens Mandarin's position as the primary language of education, official business and public spaces across China. The government says the law's provisions on social cohesion and preventing separatism benefit everyone. But minority activists abroad say it will further erode the rights of groups such as Uighurs and Tibetans. They are also warning against a clause that states China can take action against those who violate the law outside of the country. Taiwan has echoed this criticism. Its government warns the law could be used to target people there who are critical of Beijing.

The Indus Water Treaty lays out how the river's resources are to be shared between India and Pakistan. Brokered in 1960, it has survived decades of conflict between the neighbours. But recently, the agreement was put to the test after New Delhi suspended its participation. That came after an attack India said was carried out by armed groups linked to Pakistan, which it denied. This week, Islamabad has said India cannot suspend the agreement on its own. It says its share of the Indus River is a red line and threatened consequences. So, how could they avoid a further escalation?

Russia annexed Crimea in 2014. Now, more than four years into the current war, Ukraine is targeting the peninsula with increased drone attacks. In response, authorities in the Russian-controlled region have declared a state of emergency, admitting they're facing challenging times. This week, Ukraine's President Volodymyr Zelenskyy announced the start of what he called a 40-day 'influence operation' to push Russia to end the war.

"Encouraging progress." That's the feeling from mediators after the first round of talks between Iran and the US concluded in Switzerland. Those direct discussions were held to implement the memorandum of understanding. Their focus will now turn to using that agreement to negotiate a lasting peace deal within the next two months. Despite the positive atmosphere, there are hurdles to reaching a final agreement on that timeline. So, what would it take to overcome those challenges? And what concessions are the sides prepared to make to strike a deal?

Fury from Israeli ministers over the agreement US President Donald Trump has signed with Iran. And a sharp rebuke in response from his vice president JD Vance. So, what are the implications for Israel and its prime minister Benjamin Netanyahu?

Agreement between Washington and Tehran has all but ended the Iran war, with both claiming victory despite the huge cost. Among that has been Iranian damage to relationships with its Gulf neighbours which it attacked. So, what has Iran won and lost in this conflict?

Chinese president is in North Korea. Pyongyang is largely isolated on the world stage and under UN sanctions. China remains its main supporter. It's been sidelined due to its nuclear activities. But Pyongyang has made it clear it wants to be recognised as a nuclear state - and insists its programme is a "line of no retreat". Xi Jinping's visit comes after he held a summit with Donald Trump, who wants North Korea to denuclearise. He also met Vladimir Putin, who has been developing a closer relationship with Kim Jong Un. So, how could his visit shape geopolitics in the region?

Lebanon under Israeli attack while diplomatic efforts continue to end the war in Iran. And with Israel escalating attacks on Hezbollah, Tehran wants any peace deal to cover both conflicts. So, why is Iran making Lebanon a central issue in its own war?
