Ukraine's Zelenskiy says Black Sea and energy ceasefire effective immediately

KYIV, March 25 (Reuters) - Ukrainian President Volodymyr Zelenskiy said a truce covering the Black Sea and energy infrastructure was effective immediately on Tuesday and that he would seek more weapons and sanctions on Russia from Donald Trump if Moscow broke the deals.

The United States said earlier it had made separate agreements with Kyiv and Moscow to ensure safe navigation in the Black Sea and to implement a ban on strikes against energy facilities in the two countries.

"If the Russians violate this, then I have a direct question for President Trump. If they violate, here is the evidence - we ask for sanctions, we ask for weapons, etc," Zelenskiy told reporters at a news conference in Kyiv.
