"Royal Navy vessels have joined ships, aircraft and personnel from six Joint Expeditionary Force (JEF) nations to provide support to NATO and bolster security in the Baltic Sea," the ministry said in a Monday statement.

According to the release, HMS Northumberland and HMS Richmond have joined Danish frigate HDMS Niels Juel and warships from Sweden, Estonia, Latvia and Lithuania.

"JEF naval vessels escorted Danish and British supply ships as they delivered military vehicles and equipment to resupply the UK-led NATO Battlegroup in Estonia, where troops from the UK and Denmark are serving side by side," the British defense ministry said.

In addition to delivering supplies, NATO warships conducted a series of joint exercises.

BRUSSELS (Sputnik) - European Council President Charles Michel says he thinks that Russia has committed alleged war crimes in Ukraine, but it is nonetheless necessary to maintain dialogue with Russian President Vladimir Putin.

Erdogan spoke by phone on Sunday with Russian President Vladimir Putin. They agreed that the next round of talks between Russian and Ukrainian negotiators would be held in Istanbul.

Erdogan will brief his ministers on the talks he held with NATO allies on the sidelines of the extraordinary summit in Brussels on March 24.

"Since the beginning of the war in Ukraine, WHO has verified 72 attacks on health care, including 71 deaths. The right to health must be protected," Antonio Guterres said on social media.

Russia has repeatedly accused the Ukrainian paramilitary of using civilian infrastructure to attack Russian military positions, including by setting up firing sites within hospitals and residential buildings.

"During the conversation, they discussed the current events in Ukraine," the Turkish Foreign Ministry said.
