Thousands of protesters gathered outside the presidential administration building in Kyiv on June 29, to demand an end to a cease-fire in eastern Ukraine, where security forces are battling pro-Russian separatists.
The rally comes after reports of renewed clashes in eastern Ukraine, where security forces have been battling pro-Russian separatists, with five soldiers killed and at least 17 injured in Donetsk and Luhansk regions at the weekend.
The protesters also demanded that President Petro Poroshenko declare martial law in eastern Ukraine, give sufficient weapons to volunteer battalions to fight the "terrorists" and social guarantees for servicemen involved in the army's military operation in the east.
They also called on the president to demand tougher EU sanctions against Russia for supporting the separatists.
On June 27, Poroshenko extended by 72 hours a weeklong cease-fire in eastern Ukraine.
The shaky cease-fire is now set to expire on June 30.
