Russia, Ukraine, Turkey and the United Nations are expected to sign the deal later this week. * EU foreign ministers agree another 500 million euros ($504 million) of funding to supply arms to Ukraine, taking the bloc's security support to 2.5 billion euros since Russia's invasion began.

A senior Russian security official said peace in Ukraine when it came would be on Moscow's terms as Russian forces struck targets across the country with missiles even as their ground offensive stuttered. FIGHTING

* Russian missile strike in Odesa injured at least four people, burned houses to the ground, cluster shell strikes in Mkoliav injured at least two and more than 150 mines and shells fired on Sumy region, said Ukraine authorities. Russia's defence ministry said its forces had destroyed ammunition depots in Ukraine's southern Odesa region that were storing weapons supplied to Kyiv by the United States and European countries.

* At least one person was killed in a Russian missile strike on the centre of the eastern Ukrainian city of Kramatorsk, the regional governor said. * Ukraine said Russian troops tried unsuccessfully to advance towards the city of Avdiyivka north of Donetsk, but were pushed back after several days fighting, suffering heavy losses, with some 40 dead.

* Ukraine's top military commander said U.S.-supplied long-range rocket systems "stabilize the situation" through "major strikes at enemy command points, ammunition and fuel storage warehouses." * Ukrainian shelling of a hydroelectric power station in Russian-controlled territory in southern Ukraine could lead to a complete shutdown of navigation on the Dnipro river, the country's largest waterway, TASS news agency reported, citing Russian-installed authorities in the occupied Kherson region.

* Russian Defence Minister Sergei Shoigu ordered generals to prioritise destroying Ukraine's long-range missile and artillery weapons after strikes on Russian supply lines. Reuters could not independently verify the battlefield accounts.

ECONOMY * Russian gas flows via the Nord Stream 1 pipeline were seen restarting on time on Thursday after the completion of scheduled maintenance, two sources familiar with the export plans told Reuters. Russia's Gazprom had earlier told customers in Europe it could not guarantee gas supplies because of "extraordinary" circumstances, according to a letter seen by Reuters.

* Foreign allies need to increase their financial support for Ukraine to help the country maintain financial stability during the war with Russia, an adviser to the Ukrainian presidential office said. DIPLOMACY

* Russian President Vladimir Putin held talks with Supreme Leader Ayatollah Ali Khamenei in Iran, the Kremlin leader's first trip outside the former Soviet Union since Moscow's Feb. 24 invasion of Ukraine. During his visit, Putin will also hold his first face-to-face meeting since the Ukraine invasion with a NATO leader, Turkey's Tayyip Erdogan, to discuss a deal that would resume Ukraine's Black Sea grain exports. Russia, Ukraine, Turkey and the United Nations are expected to sign the deal later this week.
