Residents of the key southern Ukrainian city of Kherson are stocking up on food and water after another night of heavy Russian shelling and before an announced 56-hour curfew due to begin on Friday evening.

A number said they planned to stay indoors before the curfew and planned closure of the city, adding that they had slept in their clothes or gone to shelters because of the intensity of the Russian attack.

• Russia-Ukraine war – latest news updates

The strikes early on Wednesday, the latest in a string of attacks over the last week, come after leaked Pentagon documents suggested Ukraine would run out of missiles for its S-300 primary air defence system on Tuesday unless Kyiv could urgently find replacements.

Russia has claimed that the Black Sea grain initiative has not allowed it to export agricultural products. State-owned news agency Tass outlines this morning what Russia is looking to achieve with any extension of the deal. It writes:

The Russian foreign ministry indicated that a further decision to extend the deal would depend on the reconnection of Rosselkhozbank [Russian state-owned agricultural bank] to the Swift payment system, the resumption of supplies of agricultural machinery, spare parts and services, the lifting of restrictions on insurance and reinsurance, the lifting of the ban on access to ports, the resumption of operation of the Togliatti-Odesa ammonia pipeline, [and] unblocking foreign assets and accounts of Russian companies associated with the production and transportation of food and fertilisers.

During the meeting, some issues starting with the grain initiative will be discussed. In this regard, we can say that the sides are looking warmly at the extension of the duration. Our wish is that this initiative is extended without any trouble.

Reuters has a quick snap to say that all parties in the Black Sea grain initiative will meet for talks on Wednesday, according to a senior Ukrainian source.

The deal is, according to Russia’s timetable, due to expire on 18 May. The Kremlin has been lukewarm about the prospect of it being extended, arguing that restrictions on Russia’s banking and insurance sector have damaged the country’s own agricultural exports.

Our state has already proven that it can win. We have proven that we can liberate our land from the occupier. All those who ensure the de-occupation have proven that, together with the blue and yellow flag, normal life returns for every person and every family. Our goal is to return this life to the whole of Ukraine, to all those areas that are still temporarily under occupation.
