The ceasefire came into affect at midnight local time on Saturday - however just 14 hours later, the Azeri defence ministry said a region adjacent to Nagorno-Karabakh was under Armenian shelling.
Azerbaijan's President Ilham Aliyev has urged the global community to impose sanctions on Armenia.
On Sunday, Armenia and Azerbaijan accused each other of violating a new humanitarian ceasefire in fighting over Azerbaijan's ethnic Armenian-controlled enclave of Nagorno-Karabakh.
In order for a cease-fire to hold, a mechanism needs to be put into place in order to monitor how the sides comply with the truce, and Russian Federation was working on developing it with Armenia and Azerbaijan, he said.
President Ilham Aliyev announced Monday about the liberation of 13 more villages in the district of Jabrayil, after 27 years of Armenia's occupation in 1993.
Nagorno-Karabakh lies within Azerbaijan but has been under the control of ethnic Armenian forces backed by Armenia since a war there ended in 1994. It said Armenian forces were shelling the Azeri regions of Terter and Aghdam.
The fighting between Armenia and Azerbaijan sparked after Armenia targeted Azerbaijani positions and civilian settlements on September 27.
The Azeri Foreign Minster accepted the invitation extended by Shah Mahmood Qureshi to visit Pakistan.
"This could compromise peace and security of the entire region".
"What happened in Iraq and Syria, and even in the Balkans in the past and now in Libya and Karabakh proved that discrimination and the pursuit of small gains have lead to nothing but blood and tears", Turkish President Recep Tayyip Erdogan said.
"This is not a quick process", Nebenzya said.
Russia, France and the United States belong to the Minsk Group, which has attempted to help resolve the conflict under the umbrella of the Organisation for Security and Cooperation in Europe (OSCE).
Armenia has "become a regional and a global problem", Sentop said, noting: "Deadlock in the Caucasus will continue as long as Armenia's occupation in Nagorno-Karabakh and surrounding areas continues".
"The foreign minister expressed deep concern on the deteriorating security situation in Nagorno-Karabakh and expressed full solidarity with the brotherly nation of Azerbaijan and its people at this hard time", the statement said.
Sentop and Bayramov discussed the ongoing crisis between Azerbaijan and Armenia, and addressed Azerbaijan's operations to rescue its occupied lands. The uninterrupted bombardment triggered immediate counter-attack measures from the Azerbaijani military to push the Armenian offensive back.
Turkey has supported Baku's right to self-defence, and demanded a withdrawal of the occupying forces.
