Here's a look ahead and a roundup of key developments from the past week.
What to watch
Turkish officials are working to restore the Ukraine grain deal after Russia suspended its participation Monday. Turkey's government and the United Nations a year ago brokered the wartime deal that lets Ukraine export grain and other farm goods through the Black Sea. The deal's backers say halting it could drive up global food prices, as Ukraine has traditionally been a major grain exporter.
Observers are also watching for fallout or retaliation after an explosion on a key bridge linking the Russian mainland to the Crimea Peninsula early Monday. Russia blamed the blast on Ukraine, which has not claimed responsibility for it.
Also Monday, British Foreign Secretary James Cleverly is due to chair a meeting at the U.N. Security Council on Russia's invasion of Ukraine. The United Kingdom holds the council's rotating presidency.
On Tuesday, the U.N. General Assembly is expected to debate the situation of occupied territories of Ukraine.
What happened last week
NATO held an important summit in Lithuania with new member Finland at the table, and Ukraine waiting in the wings for a timeline to join. Ukrainian President Volodymyr Zelenskyy left the summit without a timeline but he did receive assurances for long-term backing from the United States and other allies.
Turkey dropped objections to Sweden's membership in NATO on the eve of the alliance's summit, paving the way for another NATO expansion in response to Russia's invasion of Ukraine.
The Biden administration said it wants to move forward with the sale of F-16s to Turkey after President Recep Tayyip Erdogan agreed to secure his country's approval of Sweden's NATO bid. But Congress would need to give the green light and some lawmakers have reservations about the sale.
Ukraine received cluster bombs from the U.S., the controversial weapons banned in more than 100 countries because of their danger to civilians. The Pentagon said the cluster munitions have a far lower rate of failure to explode than other cluster bombs, that would leave fewer unexploded rounds on the ground that could harm the population. Analysts and human rights workers say both Russia and Ukraine have used cluster munitions in the war. President Vladimir Putin claimed that Russia hasn't, but warned it has plenty of cluster bombs and would use them in "reciprocal action."
Belarus said Russia's Wagner Group mercenaries agreed to train Belarusian soldiers, in one of the latest developments since the mercenary group launched an attempted mutiny in Russia last month.
