What is in the 28-point US plan for Ukraine? 'Ukraine is running out of men, money and time' Can the US get all sides to end the war? Why is Europe opposing Trump's peace plan? Firefighters evacuated residents and their pets from a nine-storey apartment building in Ukraine's Sumy region after a Russian drone strike. The strikes come as Ukrainian President Volodymyr Zelenskyy met with leaders of the UK, France and Germany in London to discuss the US peace plan.

Fox News Flash top headlines are here. Check out what's clicking on Foxnews.com. An explosion in eastern Syria on Wednesday killed at least three people, according to reports. A war monitoring group said the blast was likely caused by a drone strike that targeted Iran-backed militiamen. No group claimed responsibility for an attack in the area and reports about what had happened were sketchy.

Washington, DC – Despite numerous eyewitness testimonies, investigations by media outlets and rights groups, and a Palestinian probe all determining that Israeli forces fatally shot journalist Shireen Abu Akleh, the United States has not condemned Israel for the killing. Instead, since the veteran Al Jazeera reporter was killed on May 11 in the occupied West Bank, top US officials have insisted that Israel can and should conduct an investigation. But in this US response, many advocates see a familiar script that President Joe Biden's administration has employed on more than one occasion to address Israeli violations: raise concerns, call for more information, and then move on like they never happened. "It's pretty damn thick file of abuses and murders and violations without any end or acceptable outcome as to the investigation of these crimes," Khalil Jahshan, executive director of the Arab Center Washington DC, a think tank, told Al Jazeera. "So that is continuing unfortunately, and governments on purpose bet on the short attention span of the public."

The visit to Syria, a key ally of Iran, came amid soaring tensions in the Middle East between Iran and the United States. On Friday, a U.S. drone strike killed a top Iranian general who led forces supporting Assad in Syria's civil war. Iran has vowed revenge for the slaying, and with some 600 American troops deployed in Syria, the country is a potential site of conflict with Iran. While the official statements made no mention of the U.S. killing of Iran's Revolutionary Guard Gen. Qassem Soleimani on Friday, the timing was conspicuous. Soleimani had led Iran's armed support for Assad as armed rebels neared the capital, Damascus, and he helped seize key cities, preventing the collapse of Assad's state.

BEIRUT – A research director at a military agency linked to Syria's chemical weapons program was assassinated, a newspaper close to the Syrian government reported Sunday. The pro-government al-Watan newspaper reported on its website that Aziz Esber, of the Scientific Studies and Research Center, died in a blast targeting his car Saturday night, in Syria's Hama province. It said Israel was suspected of carrying out the attack. There was no comment from Israeli or Syrian government officials. The Britain-based Syrian Observatory for Human Rights, which monitors the Syria war through local contacts, also reported Esber's death.

MOSCOW – Russia said Tuesday that a recent series of drone attacks on its military bases in Syria would have required assistance from a country possessing satellite navigation technology -- a statement that appeared to be aimed at the United States. Russia's Defense Ministry said its forces repelled a series of drone attacks Saturday on the Hemeimeem air base and a naval facility in Tartus, adding that out of the 13 drones involved, seven were shot down and six were forced to land without inflicting any damage. Without blaming any specific country, the ministry said data for the attacks could only have been obtained "from one of the countries that possesses know-how in satellite navigation." In Tuesday's statement, it noted a "strange coincidence" of a U.S. military intelligence plane flying over the Mediterranean near the two Russian bases at the moment of the attack. The Pentagon denied any involvement.

Russia has retaliated by threatening to treat American planes as targets; in a dramatic "Top Gun"-style maneuver on Monday, one of Moscow's jets buzzed within five feet of an American spy plane. None of these encounters involved the Islamic State. The contradiction opens a larger question, national security experts say, of what kind of broader strategy the Trump administration plans once the Islamic State -- now on the defensive -- is defeated in Syria. With each episode, "we own more of the conflict in Syria without articulating a strategy," said Vali Nasr, dean of the Johns Hopkins School of Advanced International Studies. "We are sleepwalking into a much broader military mandate, without saying what we plan to do afterward."

The U.S.-led coalition fighting the Islamic State group said a U.S. F-15 fighter jet shot down the drone "after it displayed hostile intent" while approaching a military camp near the Syria-Jordan border. The U.S. on Sunday shot down a Syrian jet for the first time during the conflict near Raqqa after it dropped bombs near the U.S.-allied Syrian Democratic Forces, which are battling IS. Fighting and bombardment meanwhile resumed early Tuesday between Syrian government forces and rebels in the southern city of Daraa and nearby areas, where a 48-hour truce had gone into effect on Saturday. The push by Syrian government forces in the Daraa area appears headed for the Jordanian border, two weeks after Assad's troops reached the border with Iraq for the first time in years.

WASHINGTON – The United States has concluded Russia knew in advance of Syria's chemical weapons attack last week, a senior U.S. official said Monday. The official said a drone operated by Russians was flying over a hospital as victims of the attack were rushing to get treatment. Hours after the drone left, a Russian-made fighter jet bombed the hospital in what American officials believe was an attempt to cover up the usage of chemical weapons. The official said the presence of the surveillance drone over the hospital couldn't have been a coincidence, and that Russia must have known the chemical weapons attack was coming and that victims were seeking treatment. The official, who wasn't authorized to speak publicly on intelligence matters and demanded anonymity, didn't give precise timing for when the drone was above the northern Syrian town of Khan Sheikhtoun, where more than 80 people were killed.

This 2015 file photo shows U.S. soldiers from Dragon Troop of the 3rd Cavalry Regiment discuss their mission during their first training exercise of the new year near operating base Gamberi in the Laghman province of Afghanistan. WASHINGTON – The Trump administration opened a new military front Thursday when it ordered dozens of cruise missiles against a Syrian air base, adding to a growing list of recent U.S. military forays. A look at where the United States has fought in the 21st century. After al-Qaida attacked the U.S. on Sept. 11, 2001, the U.S. led an invasion of Afghanistan that ousted the Taliban. Though the U.S. and NATO formally ended their combat mission in Afghanistan at the end of 2014, the war -- now in its 16th year -- drags on.
