Three pre-dawn firebomb attacks apparently targeting the residences of members of Greece's governing conservative New Democracy party have left five people hospitalized, authorities said Wednesday.

The attacks between 4 a.m. and 4:45 a.m. outside apartment buildings in the northern Greek city of Thessaloniki used crude explosive devices made with camping gas canisters. All the injuries were sustained from the last of the three attacks, where cars and motorcycles were set ablaze, police said.

The lines are growing at Russian gas stations -- and so is the frustration and uncertainty as several months of Ukrainian attacks have set oil refineries ablaze and choked supplies for motorists across the vast country.

Fuel rationing has been introduced in many regions, with hourslong queues of cars snaking beside roads. Social media videos show drivers aghast at the lines or swearing at empty gas pumps and rising prices. The mayor of the Siberian city of Irkutsk even ordered portable toilets brought in to accommodate those in line.

A search is underway for a suspect who fled on foot after an explosive device placed in an apartment building entrance in Monaco injured three people including a reported Ukrainian tycoon, the exclusive principality's chief prosecutor said Tuesday.

Five people were killed in a shooting on Monday at a youth welfare facility in the northern German town of Stade, police said. Two people were arrested, including the suspected shooter.

Israel's Cabinet unanimously approved a proposal on Sunday to designate violence against Armenians by the Ottoman Empire during World War I as a genocide.

The step, which still needs approval in Parliament, reflects deteriorating ties between Israel and Turkey. Turkey has fiercely lobbied to prevent countries from officially recognizing the mass deaths of Armenians around 1915 as a genocide, even as Armenians have pushed for it.

Russian missiles and drones killed at least eight civilians and injured 35 others in Ukraine on Monday in what Ukrainian President Volodymyr Zelensky described as "horrific attacks."
