A Ukrainian maritime drone explodes at a Romanian Black Sea port. No injuries reported.

CONSTANTA, Romania (AP) — A Ukrainian maritime drone that was being used in the country's war against Russia exploded Friday at a Black Sea port in Romania, while three other sea drones exploded outside the port, Romanian authorities said. No one was hurt.

The drone that self-detonated in the port of Constanta exploded at around 10:30 a.m., after the area had been secured and isolated by the Romanian Intelligence Service, coast guard and the Defense Ministry, authorities said.

“Immediately after identifying the drone, the Ministry of Defense contacted its Ukrainian counterparts, who confirmed that they had lost control of the operation of four drones,” the Romanian government said in a statement. “The other three drones self-detonated — two offshore and the third outside the port.”

“Confirmation of these events came from both the Ukrainian side and from data obtained by the Romanian authorities,” it added.

Romanian President Nicusor Dan said in a statement online that the Ukrainian forces “lost control of the assets as a result of electronic warfare actions by Russia," likely jamming, and that the drone's incursion into “Romanian sovereign space is a direct consequence of the war waged by Russia” against Ukraine.

The Ukrainian Navy confirmed in a statement that it had lost control of an unmanned naval boat “while performing tasks in the Black Sea operational zone,” and that its military was in contact with Romanian authorities "to prevent losses among the civilian population.

The incident took place a week after a Russian aerial drone that was part of an attack on Ukraine went astray and struck an apartment building in Romania’s eastern Danube port city of Galati, injuring two people in the NATO member country.

Raed Arafat, the head of Romania's Department for Emergency Situations, told a news conference Friday morning that helicopters had been deployed to search for more drones and that the authorities had issued text message alerts to residents.

“There is a possibility that there may be other drones,” he said. “We are not panicking. These are preventive measures. If there are other drones, we want to make sure there is not another explosion in an area where people are not evacuated.”

After the port explosion, more than 1,300 people were evacuated from several Black Sea beaches and the routes leading to them were temporarily blocked. Just before 3 p.m., the emergency authorities announced they had suspended evacuation measures.

The Russian Embassy in Bucharest accused Romania on Friday of intentionally releasing “incomplete information” regarding the drone's origin, and said “three other similar drones” belonging to Ukraine were drifting toward Romanian territorial waters.

“These are Ukrainian unmanned maritime vehicles, used by the Kyiv regime to commit terrorist acts against civilian ships and to create threats to the safety of navigation in the Black Sea,” the embassy said. “Any attempts to associate, directly or indirectly, these drones with Russia and to assign it responsibility for the incident are without any reason.”

The recent incidents in Romania are some of the latest in a series of drone incursions — from both Russia and Ukraine — to hit NATO members since Moscow launched its full-scale invasion of Ukraine in February 2022.

A month ago, Greece made a formal complaint to the Ukrainian government after a military sea drone carrying explosives was discovered off a Greek island. Greece determined that it was Ukrainian-built. Greek Defense Minister Nikos Dendias called it “an extremely serious issue," and the complaint was forwarded to both NATO and the EU.

Romanian forces destroyed another maritime drone in the Black Sea on Wednesday. Since the beginning of the war next door, the Defense Ministry said that the Romanian navy has neutralized nine of the 156 sea mines in the Black Sea basin.

For its part, the European Union was giving “full solidarity and support to Romania,” European Council President António Costa said Friday.

“The EU condemns the repeated violations of airspace of Member States and reaffirms its unwavering commitment to the security of all Member States,” he said in an online statement Friday. “This is the third significant security incident in Romania in recent weeks. These incidents are a direct consequence of Russia’s war of aggression against Ukraine.”

CHICAGO (AP) — Chicago Cubs president Jed Hoyer isn’t panicking over his team’s protracted slump so far this season.

Chicago entered Friday’s game against San Francisco having won six of its past 24 games and at 33-30 overall for fourth in the NL Central.

That follows a 20-3 run that drove the Cubs to a 27-12 record on May 8 when they prevailed 7-1 at Texas to complete their second of two 10-game winning streaks this season.

Chicago is just the second team in major league history to have two 10-game winning streaks and a 10-game losing streak in the same season, along with the 2017 Dodgers.

“That Friday game in Texas, I thought we looked like World Series quality at-bats in that game and we played great,” Hoyer told reporters before Friday’s game at Wrigley Field. “We haven’t really played well since then.

“We need to get back to playing like that again. We need to do it fairly soon. We got way over .500. We cashed a lot of that in, unfortunately.”

Hoyer says the Cubs, with a deep starting lineup and strong defensive play, shouldn't be wallowing at the .250 winning percentage they've had since May 9.

“Intuitively you know this group of players is too good to have this last forever,” Hoyer said, “But it’s lasted longer than we all hoped."

Hoyer said he isn’t considering deals right now or looking ahead to the Aug. 3 trade deadline.

“The trade deadline is the furthest thing from my mind right now,” Hoyer said. “I think we just have to play better. That’s the priority.”

“Our position player group is deep and it’s pretty set and so the backbone of our team is our position players."

That group showed some spark on Thursday, when the Cubs came back with four runs in the ninth inning to top the Athletics 7-6. Chicago had seven hits in the ninth after just four hits in the first eight innings, with Pete Crow-Armstrong’s single driving in the winning run.

Gold Glove outfielders Crow-Armstrong and Ian Happ have been improving at the plate after slumps.

Crow-Armstrong entered Friday on a career-high nine-game hitting streak, with a .359 average, three homers and seven RBIs in the stretch. Happ came in batting .359 with four homers and 14 RBIs in his previous nine games, boosting his average to .237.

Other Cubs need to get rolling — none more so than two-time Gold Glove shortstop Dansby Swanson. His .184 average is third lowest among regulars in the majors.

And third baseman Alex Bregman has just one homer and five RBIs over his past 21 games entering Friday.

Hoyer believes Bregman's power will return.

“Yes, water finds its own level,” he said.

Chicago’s rotation has been hit hard by injuries. Right-hander Edward Cabrera returned from a blister on his right middle finger and started Friday.

But Cade Horton is out for the season because of elbow surgery, and Justin Steele has an uncertain timeline after he had a setback in his recovery from an elbow injury. Matthew Boyd is nearing a return after he had surgery for a meniscus tear in is left knee.

Shota Imanaga and Jameson Taillon have been allowing home runs recently, however.

“Candidly, some of these slumps actually give me some comfort,” Hoyer said. ”I know it sounds strange, but we have good, established players, and they’re going to get hot and they’re going to get to their numbers.”
