Russia and Ukraine traded heavy aerial blows overnight Saturday, with both sides reporting more than 100 enemy drones over their respective territories.

Ukraine said Saturday it had downed 130 Russian-launched drones across the country at night, as international efforts to end the three-year war intensify.

The last time Ukraine signed a peace accord with Russia, 10 years ago, it brought only sporadic violence, mounting distrust, and eventually full-scale war. Here’s what we can learn from that history.

Russian President Vladimir Putin said he didn’t support an immediate cease-fire in Ukraine, calling for more discussion on a permanent end to the war as Moscow’s army made rapid gains toward expelling Kyiv’s forces from its Kursk region.

The remarks by the Russian leader suggested he wanted to draw out negotiations or make a truce impossible. Ukraine’s leader called the response to a cease-fire plan “manipulative.”

U.S. officials arrived in Moscow discuss the proposed 30-day pause in fighting between Ukraine and Russia, but Russia is wary of the deal.

Russia rejected the United States-brokered ceasefire agreement for the war in Ukraine. Yuri Ushakov, a high-level aide to Russian President Vladimir Putin, dismissed the bid as a move to help Ukraine regroup while it’s on the back foot.

President Vladimir Putin of Russia did not outright reject U.S. President Trump’s ceasefire plan for Ukraine but is not ready to sign it.

US negotiators travelled to Russia on Thursday to present their plan for a 30-day ceasefire in Ukraine, but Moscow warned in advance it would refuse any temporary deal that gave Kyiv a "breather".Ukraine agreed to the plan during talks with US officials in Saudi Arabia on Tuesday,
