KYIV, Oct 11 - Russian forces fired more missiles and munition-carrying drones at targets in Ukraine on Tuesday, prompting G-7 summit to issue a warning about Moscow potentially committing war crimes.

The summit’s emergency meeting came a day after Russia has unleashed a major missile attack on Ukraine, killing at least 19 and destroying much of the Ukrainian energy sector.

President Volodymyr Zelensky, who addressed the G-7 leaders during a virtual meeting, said Russia had fired more than 100 missiles and dozens of drones at Ukraine, and while Ukraine shot many of them, it needs “more modern and effective” aid defense system.

The leaders of the Group of Seven industrial powers condemned the bombardment and said they would “stand firmly with Ukraine for as long as it takes.”

Russia launched the widespread attacks in retaliation for a weekend explosion that damaged the Kerch Bridge between Russia and the Crimean Peninsula, which Moscow annexed in 2014. Russian President Vladimir Putin alleged that Ukrainian special services masterminded the blast. The Ukrainian government has applauded it but not claimed responsibility.

The G-7 leaders reaffirmed their “commitment to providing the support Ukraine needs to uphold its sovereignty and territorial integrity,” adding that the “indiscriminate attacks on innocent civilian populations constitute a war crime.”

The Pentagon earlier announced plans to deliver the first two advanced NASAMs anti-aircraft systems to Ukraine in the coming weeks. The systems, which Kyiv has long wanted, will provide medium- to long-range defense against missile attacks.

In a phone call with Zelensky on Tuesday, President Joe Biden “pledged to continue providing Ukraine with the support needed to defend itself, including advanced air defense systems,” the White House said.

Zelensky thanked the U.S. and also Germany for speeding up the delivery of the first of four promised IRIS-T air defense systems. Ukraine’s defense minister tweeted that the German system had just arrived, and that a “new era” of air defense for Ukraine had begun.

Zelensky also urged the G-7 leaders to respond “symmetrically” to the attacks on the Ukrainian energy sector by doing more to stop Russia from profiting off its exports of oil and gas.

“Such steps can bring peace closer,” he said. “They will encourage the terrorist state to think about peace, about the unprofitability of war.”

Ukrainian officials said the diffuse strikes on power plants and civilian areas made no “practical military sense.” However, Putin’s supporters had urged the Kremlin for weeks to take tougher action in Ukraine and criticized the Russian military for a series of embarrassing battlefield setbacks.

The head of Britain’s cyber-intelligence agency, Jeremy Fleming, said Tuesday in a rare public speech that Russia is running out of military supplies and struggling to fill its ranks.

“Russia’s forces are exhausted,” Fleming said. “The use of prisoners as reinforcements, and now the mobilization of tens of thousands of inexperienced conscripts, speaks of a desperate situation.”

Like Monday’s strikes, the bombardment Tuesday struck both energy infrastructure and civilian areas. One person was killed when 12 missiles slammed into the southern city of Zaporizhzhia, setting off a large fire, the State Emergency Service said. A local official said the missiles hit a school, residential buildings and medical facilities.

Energy facilities in the western Lviv and Vinnytsia regions also took hits. Officials said Ukrainian forces shot down an inbound Russian missile before it reached Kyiv, but the capital region experienced rolling power outages as a result of the previous day’s strikes.

The State Emergency Service said 19 people died and 105 people were wounded in Monday’s strikes. At least five of the victims were in Kyiv, Mayor Vitali Klitschko said. More than 300 cities and towns lost power. (ap/ez)
