Good morning.

Iran has warned the US that it is prepared to confront any ground assault, accusing Washington of secretly planning a land attack while publicly seeking talks, as the war that has killed thousands of people and caused the biggest ever disruption to global energy supplies entered its second month.

In a message published to mark 30 days since the start of the war, the Iranian parliament speaker, Mohammad Bagher Ghalibaf, said: “The enemy signals negotiation in public, while in secret it plots a ground attack.”

“Our firing continues,” Ghalibaf said. “Our missiles are in place. Our determination and faith have increased.” He said Iranian forces were “waiting for the arrival of American troops on the ground to set them on fire and punish their regional partners for ever”.

What has Donald Trump said? In an interview published last night, the president did little to assuage those concerns, telling the Financial Times that his “preference would be to take the oil” in Iran, and saying of Iran’s crucial export hub on Kharg Island: “We could take it very easily.”

Trump appears to relax de facto oil blockade on Cuba as Russian oil tanker arrivesA fuel tanker in Matanzas Bay in Cuba in February. Photograph: EPA

Donald Trump has signalled a new flexibility in allowing oil into Cuba, hours before a Russian oil tanker under US sanctions arrived at the Caribbean island amid a de facto oil blockade imposed by Washington.

Speaking to reporters onboard Air Force One, the president said: “If a country wants to send some oil into Cuba, right now, I have no problem whether it’s Russia or not.”

Until now, Trump’s administration had in effect prevented all oil shipments to Cuba in an attempt to put pressure on the government in Havana, while also issuing a series of threatening statements.

Why is this important to Cuba? The thousands of barrels of crude would provide significant relief to Cuba, which, according to its president, Miguel Díaz-Canel, has not received any oil imports for three months, leading to strict rationing of gasoline and exacerbating an energy crisis that has resulted in multiple power outages across the country.

Cory Booker says Democrats have ‘failed this moment’ and calls for new leadersCory Booker speaking to the press last week. Photograph: Kena Betancur/AFP/Getty Images

Cory Booker, the Democratic senator from New Jersey, renewed his calls for new leadership of the Democratic party, saying it had “failed this moment”.

“As a whole, our party has failed this moment,” Booker said yesterday. “I’ve called for a generational renewal, because this left-right divide is killing our country and our adversaries know it.”

During an interview on NBC’s Meet the Press, Booker also said the Democratic party had “too small of a coalition”, especially as the party sought to confront “new challenges”.

Do other Democrats agree with him? Some Democrats, specifically on the more progressive wing of the party, have discussed replacing Chuck Schumer, the minority leader, as midterm elections approach. Progressive senators reportedly see Schumer as an obstacle to standing up to Trump.

The war on Iran is the most unpopular a US war has ever been at its onset, but this dramatic shift in sentiment has not yet translated into organized anti-war opposition. But there’s no reason to succumb to despair, because opposition can be rebuilt, write Salar Mohandesi, an associate professor of history at Bowdoin College, and Ben Mabie, a member of the editorial collective for the quarterly magazine Long-Haul.

Almost 30 years after the intricate web of nerves inside the penis was plotted out, the same mapping has finally been completed for the clitoris. As well as revealing the extent of the nerves that are crucial to orgasms, the work could help prevent women who have pelvic operations from ending up with poorer sexual function.

How does a kangaroo escape a petting zoo? It’s not the opening line to a dad joke. If you’re Chesney the kangaroo, you scale an 8ft (2.5-meter) fence and go on the lam for three days, sending residents of a small Wisconsin town on a search that would end happily on Saturday.
