Ukraine needs a "serious" contribution from Europe of troops who are ready to fight, and not peacekeepers, after any end of hostilities with Russia, senior aide to President Volodymyr Zelensky, Igor Zhovkva, says. Ukrainian President Zelensky will hold talks with French President Emmanuel Macron on Wednesday, ahead of the Thursday gathering of leaders from the so-called "coalition of the willing," a British-French led group of countries considering deploying peacekeeping troops to Ukraine should a ceasefire be reached.
