Amid Nagorno-Karabakh clash, Rouhani’s chief of staff tells Azeri official Tehran still respects territorial integrity.
Here are the latest updates:
The defence ministry of the breakaway region of Nagorno-Karabakh said it could report 23 more casualties.
Dozens have been reported killed and hundreds wounded in fighting since Sunday.
Iranian media reported that a rocket has landed on Iranian soil as part of the Nagorno-Karabakh conflict.
The missile reportedly landed close to a residential area in a village called Mohammad Salehlou located in Khoda Afarin county, near the Armenian border. It is unclear who fired the rocket. No casualties or damages were reported.
This is the fourth rocket that lands in the Khoda Afarin border area. All three previous rockets had landed in non-residential areas, inflicting no casualties or damages.
Russian Foreign Ministry said that illegal armed groups coming from Syria and Libya were being sent to the disputed Nagorno-Karabakh region, according to a statement.
Moscow called on both parties to prevent the use of foreign fighters and mercenaries in the conflict.
Two Syrian rebel sources have told Reuters that Turkey is sending Syrian rebel fighters to support Azerbaijan, which Turkey and Azerbaijan have denied.
Russian Foreign Minister Sergey Lavrov said that Moscow was willing to host the foreign ministers of Armenia and Azerbaijan for talks, a ministry statement cited him as saying.
He said Russia would continue to work both independently and together with other representatives of the Minsk group of the Organization for Security and Cooperation in Europe (OSCE) to mediate in the conflict.
One person was killed and three wounded by Armenian fire on the town of Horadiz in southern Azerbaijan, said the Azeri Prosecutor’s Office.
Al Jazeera’s Robin Forestier-Walker, who has extensively covered developments in the region, said that videos being released from the contested region give the idea of “an all-out war”.
“The most committed observers to this conflict said that this is the worst they have seen since the ceasefire in 1994 that sort of froze this conflict.”
Both sides are making claims about how much success they had in the number of military infrastructures they destroyed. “It’s quite extraordinary,” said Forestier-Walker, adding that the Armenians reported destroying 137 tanks and armoured vehicles, 72 aerial vehicles, seven helicopters and aircraft.
“Azerbaijan is also making similar claims, perhaps in larger numbers, but certainly when we see the military videos that have been released – and some are really ghastly – it gives a sense that this is really an all-out war of the like we haven’t seen since the ’90s.”
Azerbaijan pledged to pursue military action against Armenian forces until their full withdrawal from the disputed territory.
“We only have one condition: Armenian armed forces must unconditionally, fully, and immediately leave our lands,” Azerbaijani President Ilham Aliyev said in televised remarks.
If “the Armenian government fulfils the demand, fighting and bloodshed will end, and peace will be established in the region,” he added.
The two rival countries have so far rejected international calls for a halt to fighting and negotiations.
Azerbaijan’s President Ilham Aliyev has thanked Turkish President Recep Tayyip Erdogan for his support, as fighting between Azerbaijan and ethnic Armenian forces entered a fourth day over the breakaway region of Nagorno-Karabakh.
Erdogan said on Monday Azerbaijan must take matters into its own hands and Turkey would stand “with all its resources and heart” behind Baku.
Aliyev said Pakistan, Afghanistan and Turkey all demonstrated support, but added Azerbaijan’s army did not need external help.
Armenia says three civilians have been killed in Martakert, a town situated in the breakaway region of Nagorno-Karabakh, as a result of an Azeri attack, the state-run Armenpress news agency reported.
The Kremlin has said Russia’s military was closely following developments over Nagorno-Karabakh and again urged the opposing sides to end hostilities.
Armenia has posted pictures on an online government platform of the wreckage of a plane it said was a SU-25 warplane, shot down by a Turkish fighter jet on September 29.
Turkey and Azerbaijan have denied Yerevan’s claim that a Turkish F-16 fighter jet shot down the Armenian plane, killing the pilot. On Wednesday, Armenia’s defence ministry named the pilot as Major Valeri Danelin.
Turkey will back Azerbaijan with “every means available” in the Nagorno-Karabakh conflict, Foreign Minister Mevlut Cavusoglu has said.
“We will do what is necessary … if Azerbaijan wants to resolve this [conflict] on the field,” Cavusoglu told state news agency Anadolu after being asked whether Turkey is providing military support to Baku.
Azerbaijan currently has the “capacity” to handle the situation on its own, Cavusoglu said.
Turkish Foreign Minister Cavusoglu has said French solidarity with Armenia amounted to supporting Armenian occupation in Azerbaijan.
He was speaking in an interview with state-run Anadolu news agency after French President Emmanuel Macron said Turkey’s “warlike” rhetoric was encouraging Baku to reconquer Nagorno-Karabakh.
French President Macron has said Turkey’s “warlike” rhetoric was encouraging Azerbaijan to reconquer Nagorno-Karabakh and that was unacceptable, though he added he had no proof at this stage of direct Turkish involvement.
Fierce fighting broke out on Sunday between Armenian and Azeri forces over Nagorno-Karabakh. Turkey is an ally of Azerbaijan, with which it shares ethnic and cultural ties.
“I have noted Turkey’s political declarations [in favour of Azerbaijan], which I think are inconsiderate and dangerous,” Macron told a news conference in Latvia.
Armenia’s Prime Minister Nikol Pashinyan, who spoke by phone to Russian President Vladimir Putin on Tuesday, said he is not at this point considering asking for help under a post-Soviet security treaty – but did not rule out doing so.
“Armenia will ensure its security, with the participation of the Collective Security Treaty Organization (CSTO) or without it,” Russian news agencies quoted Pashinyan as saying.
He said he and Putin had not discussed the possibility of Russian military intervention in the Nagorno-Karabakh conflict.
Russia has used the CSTO, along with the Eurasian Economic Union, another regional bloc focused on trade, to project influence across most of the former Soviet Union.
Armenian Prime Minister Nikol Pashinyan says peace talks with Azerbaijan under Russian mediation would be inappropriate, as fighting over the breakaway Nagorno-Karabakh region entered a fourth day.
“It isn’t very appropriate to speak of a summit between Armenia, Azerbaijan and Russia at a time of intensive hostilities,” Pashinyan told Russia’s Interfax news agency. “A suitable atmosphere and conditions are needed for negotiations.”
At least 2,300 Armenian soldiers have been killed or wounded by Azerbaijani troops since the conflict between the two countries began on Sunday, Azerbaijan’s defence ministry has said, according to an Anadolu Agency report.
Al Jazeera was not able to independently identify these numbers.
The ministry statement added that 130 tanks and armoured vehicles, more than 200 artillery and missile systems, approximately 25 air defence systems, six command and observation zones, five ammunition depots, 50 anti-tank guns and 55 cars were also destroyed.
