AlQa'dah 03, 1436, August 18, 2015, SPA -- Ukrainian President Petro Poroshenko is due to visit Brussels before the end of this month, a spokeswoman for the European Commission said Tuesday, as a recent surge in violence casts renewed doubts on a ceasefire for the conflict-ridden country, dpa reported. Skirmishes between government forces and pro-Russian separatist rebels in recent days around the eastern port city of Mariupol have led to several deaths, including at least two civilians, local media reported. "Commission President Jean-Claude Juncker, spoke Tuesday to Poroshenko about the current situation in Ukraine and the implementation of the Minsk agreement," said spokeswoman Annika Breidthardt, adding that they agreed to meet in the Belgian capital this month. Poroshenko is also scheduled to meet with German Chancellor Angela Merkel and French President Francois Hollande in Berlin on Monday, French Foreign Minister Laurent Fabius said Tuesday in Paris.
