European leaders are expected to cement support for Ukraine Monday as it faces Washington's pressure to swiftly accept a U.S.-brokered peace deal.

After Sunday's talks in Berlin between U.S. envoys and Ukrainian President Volodymyr Zelensky, Ukrainian and European officials are set to continue a series of meetings in an effort to secure the continent's peace and security in the face of an increasingly assertive Russia.

Australian Prime Minister Anthony Albanese on Monday proposed tougher national gun laws after a mass shooting targeted a Hanukkah celebration on Sydney's Bondi Beach, leaving at least 15 people dead.

Albanese said he would propose new restrictions, including limiting the number of guns a licensed owner can obtain. His proposals were announced after the authorities revealed that the older of the two gunmen — who were a father and son — had held a gun license for a decade and amassed his six guns legally.

Two suspected shooters opened fire at Sydney's iconic Bondi Beach on Sunday, killing nine people and wounding multiple others in an attack that spread panic, with bodies reported lying on the ground.

U.S. President Donald Trump's special envoy will meet with Volodymyr Zelensky and other European leaders in Berlin this weekend, the White House said, as Washington presses for a plan to end Russia's war with Ukraine.

Turkish President Recep Tayyip Erdogan on Saturday warned that the Black Sea should not turn into an "area of confrontation" between Russia and Ukraine, after several strikes in recent weeks.

Germany has said it will send a group of soldiers to Poland to help with a project to fortify the country's eastern border as worries mount about the threat from Russia.

A senior Kremlin official says that the Russian police and National Guard will remain in eastern Ukraine's Donbas to oversee the prized industrial region, even if a peace settlement ends the nearly four-year war — a possibility that is likely to be rejected by Ukrainian officials as U.S.-led negotiations drag on.

Moscow will give its blessing to a ceasefire only after Ukraine's forces have withdrawn from the front line, Kremlin adviser Yuri Ushakov said in comments published Friday in Russian business daily Kommersant.

Authoritarian President Alexander Lukashenko on Friday hosted a U.S. envoy for talks in the Belarus capital of Minsk, the latest step in the isolated leader's effort to improve ties with the West.

Lukashenko met with U.S. special envoy for Belarus John Coale, according to state news agency Belta and the presidential press service. The press service said the talks would continue Saturday.

Germany summoned Russia's ambassador Friday following accusations of sabotage, cyberattacks and election interference, an official said.

The German government has also accused Moscow of perpetrating disinformation campaigns.

A 6.7 magnitude earthquake shook northeastern Japan and caused small tsunami waves but no apparent damage Friday, days after a stronger quake in the same region.

Friday's quake occurred off the east coast of Aomori prefecture, in the north of Honshu, the main Japanese island, at a depth of 20 kilometers (12.4 miles) at 11:44 a.m., according to the Japan Meteorological Agency, which issued a tsunami advisory that was lifted about two hours later.
