The U.S. deported hundreds of immigrants after President Donald Trump invoked the Alien Enemies Act for the first time since World War II, using the sweeping powers of a centuries-old wartime law to target alleged members of a Venezuelan gang. The deportations over the weekend came as a federal judge issued an order temporarily barring them.

The act gives allows noncitizens to be deported without the opportunity to go before an immigration or federal court judge. Trump's Saturday proclamation called the Tren de Aragua gang an invading force.

A ceasefire in Russia's 3-year-old war in Ukraine hinges on Moscow accepting the U.S. proposal of a 30-day pause in fighting as a confidence-building measure for both sides to hammer out a longer-term peace plan.

Ukrainian President Volodymyr Zelenskyy has warned that Russian President Vladimir Putin will look to delay such a temporary truce with conditions meant to divert the peace process and lengthen the war. Ukraine, which faced pressure to accept the ceasefire after U.S. President Donald Trump blocked military aid and intelligence sharing, expects that he will threaten more sanctions on Moscow to push Putin into accepting the terms.

With U.S. support for Ukraine in doubt, Kyiv's European allies are weighing whether to seize $300 billion in frozen Russian assets and use the money to compensate Ukraine, support its military and help rebuild shattered homes and towns.

For now, the assets are still on ice, with opponents of seizure warning that the move could violate international law and destabilize financial markets.

Peru's president declared a state of emergency in the capital Monday and ordered the deployment of soldiers to help police address a surge of violence, amid widespread outcry a day after the killing of a popular singer.

President Dina Boluarte's government published a decree saying that the state of emergency will last 30 days, and authorities will restrict some rights, including the freedom of assembly and movement. That means the police and the army would be able to detain people without a judicial order.

Israel launched a wave of airstrikes across the Gaza Strip early Tuesday, saying it was hitting Hamas targets in its heaviest assault in the territory since a ceasefire took effect in January.

U.S. Homeland Security officials said that a doctor from Lebanon who was deported over the weekend despite having a U.S. visa "openly admitted" to supporting slain Hezbollah leader Sayyed Hassan Nasrallah and attending his funeral.

The department's statement, posted on social media, provides a possible explanation for Dr. Rasha Alawieh's deportation, which has sparked widespread alarm in the U.S., especially after a federal judge ordered that she not be removed until a hearing could be held. Government lawyers have said customs officials did not get word until after Alawieh was sent back to Lebanon.

The Lebanese health ministry says at least seven people were killed and 52 wounded in clashes on the border with Syria that erupted on Sunday night.

President Joseph Aoun said that the Lebanese Army would respond to incoming fire from neighboring Syria that authorities said had killed a child.

Clashes broke out late Sunday at the Syrian-Lebanese border, with the new authorities in Damascus accusing Hezbollah of abducting three soldiers into Lebanon and killing them.
