Nagorno-Karabakh coflict

The EU's top diplomat on Sunday expressed his deep concern over reports of violations of a ceasefire between Armenia and the Azerbaijan Republic in the disputed Nagorno-Karabakh region.

Iran PressEurope: "We note with extreme concern the reports of continued military activities, including against civilian targets, as well as civilian casualties," EU foreign policy chief Josep Borrell said in a statement.

The EU's 27 member states "urge the warring sides to ensure full respect of the agreement on the ground," Borrell added.

Borrell pushed the sides to engage in substantive negotiations without delay under the auspices of the Minsk Group, AFP reported.

The statement came after a ceasefire on Saturday was swiftly broken by more fighting, with both sides accusing the other of responsibility.

Borrell welcomed the ceasefire and called on all sides to strictly abide by it.
