NATO's secretary general says the alliance's member countries have failed to deliver in time what they promised to Ukraine. Jens Stoltenberg said during a visit to Kyiv that “serious delays in support have meant serious consequences on the battlefield." Russia is hurrying to exploit its advantages before Kyiv’s depleted forces get more Western military supplies. Ukraine's president says new Western supplies have started arriving, but slowly. Stoltenberg says more weapons and ammunition are on the way, including Patriot missile systems to defend against heavy Russian barrages. In other developments, Sophie, the Duchess of Edinburgh made an unannounced visit to Ukraine – the first British royal to travel to the country since Russia’s 2022 invasion.

Congress has given one of its highest final tributes, a lying in honor ceremony at the Capitol, to Medal of Honor Recipient Ralph Puckett Jr. He led an outnumbered company in battle during the Korean War and was the last surviving veteran of that war to receive the Medal of Honor. Puckett, who retired as an Army colonel, died earlier this month at the age of 97 at his home in Columbus, Georgia. He was awarded the Medal of Honor, the nation’s highest military honor, in 2021, seven decades after his actions during the Korean War. The lying in honor ceremony at the Capitol is reserved for the nation’s most distinguished private citizens. Only seven others have received the honor.

Palestinian health officials say Israeli airstrikes on the southern Gaza city of Rafah have killed at least 22 people, including six women and five children. One of the children killed in the strikes overnight into Monday was just 5 days old. Israel has regularly carried out airstrikes on Rafah since the start of the war and has threatened to send in ground troops. Israel says Rafah is the last major Hamas stronghold in Gaza. Over a million Palestinians have sought refuge in the city. The U.S. and others have urged Israel not to invade the city, fearing a humanitarian catastrophe. U.S. Secretary of State Antony Blinken on Monday began his seventh diplomatic mission to the Middle East since the Israel-Hamas war began in October.

A U.S. Navy ship and several Army vessels involved in an American-led effort to bring more aid into the besieged Gaza Strip are offshore from the enclave and building out a floating platform for the operation. The Pentagon said Monday the construction and operation of the pier and aid delivery will cost at least $320 million. U.S. officials have confirmed the ongoing construction off the Gaza coast. The U.S. and Israel have said they hope to have the mobile pier in place and operations underway by early May. Aid has been slow to get into Gaza, with long backups of trucks awaiting Israeli inspections.
