"We, Estonia, Latvia and Lithuania Foreign Ministers, call on Germany to provide Leopard tanks to Ukraine now," Estonia's Foreign Minister Urmas Reinsalu said on Twitter.
"This is needed to stop Russian aggression, help Ukraine and restore peace in Europe quickly. Germany as the leading European power has special responsibility in this regard."
The tweet comes after Germany and Western allies reached no decision on whether Berlin would agree to send its Leopard 2 tanks to Ukraine or permit other countries that have them to do so.
Russia in recent days has increased shelling of Ukraine's eastern regions over outside the main front line in Donbas, with Russia's defence ministry saying on Saturday its offensive in the Zaporizhzhia region had put its army's units in more advantageous positions.
Germany's new Defence Minister Boris Pistorius said on Saturday he plans to visit Ukraine "quickly," adding that Berlin is in "close dialogue" on the issue of tanks with the United States and other international partners.
