Ukrainian President Volodymyr Zelensky arrived in Estonia on Tuesday to attend a summit of Nordic and Baltic leaders, a visit that comes amid friction over Ukrainian drones straying into the region in recent months.

The drones have crashed into the chimney of a power plant in Estonia, hit empty fuel tanks in Latvia and been shot down by Romanian fighter jets stationed in Lithuania. Ukrainian officials apologized, saying the drones had been aimed at military targets inside Russia but were sent off course by Russian electronic interference.

Chinese President Xi Jinping and North Korean leader Kim Jong Un underscored their commitment to deepen cooperation in a closely watched summit on Monday, as Xi made a rare visit to Pyongyang in a likely attempt to reassert Beijing's unique influence over its socialist neighbor.

It's Xi's first visit to North Korea in seven years. Earlier Monday, he was given a lavish welcome upon arrival at Pyongyang's international airport. He and his wife Peng Liyuan were greeted by Kim and his wife Ri Sol Ju, who broadly smiled and clapped.

Ukrainian forces struck oil facilities in Russia and occupied Ukraine, Ukrainian and Russian officials said on Monday, as part of their campaign aimed at making Moscow pay an economic cost for the war.

Separately, Ukraine's President Volodymyr Zelenskyy has confirmed that Roman Abramovich acted as a go-between for messages between Kyiv and Moscow.

At least 17 people were killed in a southern Philippine province Monday mostly due to a landslide set off by a 7.8-magnitude earthquake, bringing the overall death toll wrought by the quake in the region to 32, officials said.

Rene Punzalan, a disaster-mitigation official of Sarangani province told the DZBB radio network that 13 villagers were killed when a landslide set off by the earthquake hit houses in the mountainous town of Glan. Four other villagers died in Sarangani for still-unclear unclear reasons, he said.

U.S. President Donald Trump said Sunday he will call Israeli Prime Minister Benjamin Netanyahu to urge him not to retaliate against Iranian missile strikes on Israel, U.S. news outlet Axios reported.

"I am going to call Bibi right now and tell him not to retaliate," Trump was quoted as saying by Axios journalist Barak Ravid in a phone interview, using the Israeli leader's nickname.

Air raid sirens sounded in Israel on Sunday as its military worked to intercept barrages of incoming Iranian missiles for the first time since an April ceasefire took hold in the Middle East war.

The Israeli army reported the attack just hours after Tehran had threatened to retaliate for a new Israeli strike on Beirut's southern suburbs.

Iran threatened to retaliate against the United States and Israel for fresh strikes in Beirut's southern suburbs on Sunday, further dampening hopes for a lasting peace as the Middle East war reached its 100th day.

The United States said it shot down a pair of Iranian drones threatening the Strait of Hormuz, the latest escalation of violence as the war crept into its 100th day on Sunday with no end in sight.

Iran still has "21, 22 percent" of its missiles left, U.S. President Donald Trump said, in a week in which Tehran fired dozens of them toward regional neighbors, despite a sputtering ceasefire.

The release of frozen Iranian funds has become a key issue in negotiations between Tehran and Washington aimed at ending their war, a senior Iranian official said.
