Pope Leo XIV lands in Angola for third leg of his journey
Pope Leo XIV has arrived in Angola, marking the third leg of his multi-country Africa tour after previous stops in Algeria and Cameroon. He landed in Luanda for a three-day visit that will include meetings with political leaders and large public gatherings, as part of a broader effort to engage with one of the world’s fastest-growing Catholic regions. The visit comes as the Pope continues to emphasise themes of peace, social justice and governance, while seeking to strengthen the Church’s presence across Africa.
Iran says gaps remain in US talks as Trump cites ‘very good conversations’
Iran has said significant gaps remain in ongoing negotiations with the United States, despite recent talks showing some limited progress. Tehran pointed to unresolved disagreements over key issues, including its nuclear programme and control of the Strait of Hormuz, indicating that a final deal is still distant. Meanwhile, Trump described the discussions as “very good conversations,” highlighting a contrast in tone between the two sides as a fragile ceasefire continues.
North Korea launches ballistic missiles towards sea off its east coast
North Korea has launched multiple ballistic missiles toward waters off its east coast on Sunday, in what officials say is the latest in a series of weapons tests this year. The missiles were fired from the Sinpo area and travelled roughly 140 kilometres, with South Korea, the United States and Japan all confirming the launches and closely monitoring the situation. Seoul condemned the tests as a violation of UN Security Council resolutions, warning they risk further escalating tensions on the Korean Peninsula.
At least six killed in Kyiv as gunman opens fire and takes hostages
At least six people have been killed in Kyiv after a gunman opened fire on civilians before taking hostages inside a supermarket in the city’s Holosiivskyi district. The attacker barricaded himself inside the store during a roughly 40-minute standoff with police, killing one hostage before Ukrainian special forces stormed the building and shot him dead. Around 14 others were injured, and authorities have launched a terrorism investigation into the incident, with the motive still unclear.
Australia’s most-decorated soldier vows to fight war crime charges
Former Australian soldier Ben Roberts-Smith has publicly denied allegations of war crimes in Afghanistan, saying he “categorically” rejects claims he was involved in the murder of unarmed civilians. The decorated veteran, who has been charged with five counts of war crime murder linked to incidents between 2009 and 2012, said he acted within the rules of engagement and expressed pride in his military service. Speaking after being released on bail, Roberts-Smith said he intends to fight the charges and clear his name, with the case expected to take years to proceed through the courts.
Why the Russian Army Will First Focus On Kostiantynivka
Today we zoom in on the Kostiantynivka frontline, as pressure continues to mount on the defenders of the important Donbas defensive node.

Mashovets Kostiantynivka review
“Russia has entered a critical stage of the Kostiantynivka campaign, concentrating forces from several army groupings in what appears to be one of its priority operational sectors. The immediate objective is to seize Kostiantynivka and Druzhkivka, which would open the southern and southeastern approaches to the larger Sloviansk-Kramatorsk defensive agglomeration. To support this effort, Russian command has reinforced the sector with units from multiple formations — including elements drawn from AG Centre and AG Dniepr to supplement AG South own 8th Army and 3rd AC — indicating both the importance of the objective and the difficulty of achieving it with local forces alone.” (@Vitaly via X summary)
I largely agree with Kostiantyn Mashovets’ analysis here. We have described Kostyantynivka as the ‘underbelly’ of the Sloviansk–Kramatorsk defence network, largely because it sits on roughly the same elevation as the two cities. This will be an early objective for the Spring–Summer offensive that is due to begin any day now. And we know this because the Russians have been continuously prioritising their FAB and drone strikes on Kostyantynivka since the second half of 2025. It’s also one of the most vulnerable frontline towns. I would describe Kostyantynivka’s current situation as similar to that of Pokrovsk in June–July — many infiltrations that are continually passing through. View: Failed Russian assault on Chasiv Yar positions
However, what separates Pokrovsk and Kostyantynivka is that the latter has two forward defensive nodes that have proved essential in slowing down Russian entry into the town. I have marked these two in the green circles. Chasiv Yar continues to be an absolute hair-puller for Russian units there. The Ukrainian defence in this sector has essentially blocked any flanking manoeuvre east of Kostyantynivka for close to a year now. Even in the last few days, another mechanised assault was attempted and failed, which we have linked below. The other node is Ivanopillia, which has also been troublesome — if anything, the entire main route from Toretsk to Ivanopillia has been complicated. There were a few Ukrainian soldiers who were essentially stuck behind enemy lines south of Pleshchiivka for months in 2025, complicating the consolidation and expansion process for the Russian units based there.

Dafuq is going on? Should I be in a bunker or something?
TODAY IN HISTORY (April 19, 1943): The Warsaw Ghetto Uprising, a ferocious act of armed resistance by Polish Jews against efforts by Nazi troops to destroy the ghetto and its residents, began. It lasted four weeks. Although more than 40,000 Jews were ultimately killed or deported, the uprising was a revolution in Jewish history.
Russian units have used two main entry points, which I have circled in yellow, to infiltrate the city. These are likely going to be ‘breaking point’ areas that may eventually force Ukrainian units to pull back from the current frontlines. However, as of right now, infiltration, while common, has largely not been able to consolidate in the town itself. But as we have seen in Pokrovsk, it does not require much for a break to happen.
I don’t expect too see much Rusyn Yar mainly due to the terrain and distance from Kostiantynika. I would wager the units closer to the Dobropillya salient will be used to push north-west rather than Druzhkivka. Vitaly also believes this based on OSINT research suggesting Russian units here are facing westwards rather than east.
