Speaking at a meeting in Baku with Herbert Salber, the European Union’s special envoy for the South Caucasus region, Aliyev said Armenia is dragging its feet on peace talks.

"The status-quo cannot be maintained,” the Azerbaijani leader said, according to state news agency Azartac.

Four Armenian and three Azerbaijani troops have been confirmed killed in exchanges of fire in the past week.

Armenian captured nearly one-fifth of Azerbaijan’s internationally-recognized territory, including Nagorno-Karabakh and seven adjacent districts, in a war in the early 1990s.

While large-scale hostilities ended with a ceasefire in 1994, no peace agreement has been signed.

Armenia refused to comply with four UN Security Council resolutions demanding immediate and unconditional withdrawal from the Azerbaijani territory.
