Kyrgyzstan's president said Thursday he had no intention of resigning, as rival politicians claiming leadership positions dug in for a confrontation and Russia pushed security forces to restore order. A disputed parliamentary vote has sparked a fresh crisis in the volatile Central Asian country, triggering protests and unrest that have left at least one dead and hundreds injured. On Thursday President Sooronbay Jeenbekov's office said that voluntary resignation "was not under question" as he held talks with different political factions. Jeenbekov has made no public appearances since the unrest broke out Monday and self-appointed law enforcement chiefs have said that they do not know where he is. Opposition parties claim Sunday's election was rigged by massive vote-buying in favour of parties close to Jeenbekov. The results of the vote were annulled on Tuesday, but that has done little to ease tensions, as rival politicians and their supporters press claims to leadership posts and state institutions are in chaos. Omurbek Suvanaliyev, who has claimed the title of national security chief in the aftermath of clashes between police and protesters, told Russian news agency Interfax that the government had ordered national borders closed. "For security reasons, a decision was taken to close the borders," said Suvanaliyev. The border service confirmed to AFP that the order had taken effect. Suvanaliyev is one of several politicians who claimed titles after a rally against the vote results turned violent and protesters seized the main seat of government. But on Thursday he appeared to emerge as an important player, when Kremlin spokesman Dmitry Peskov confirmed he had held talks with the head of Russia's Federal Security Service (FSB). The FSB was supporting the Kyrgyz security service in its efforts "to prevent the situation in the country from sliding into chaos," Peskov told reporters. Russia said earlier this week that it had beefed up security at a military base near the capital Bishkek. The ex-Soviet state, which borders China, has seen two popular uprisings and three of its presidents either jailed or sent into exile since independence in 1991. Jeenbekov has ruled Kyrgyzstan since 2017. Suvanaliyev, whose claimed office is constitutionally under presidential command, said he had no idea where the president was. He also cast doubt on a populist politician's claim to be prime minister. Sadyr Japarov was serving an 11.5-year sentence for hostage-taking and other crimes before he was released from jail by his supporters on Monday. The parliamentary press service said he was backed by a majority of lawmakers to become prime minister during a session held in a three-star hotel less than 24 hours later. Supporters interviewed by AFP on Thursday outside the building where the prime minister's office is located insisted Japarov was the only politician that could take Kyrgyzstan forward. "All the solutions to our problems are inside Sadyr's head, inside this book," one said, showing an AFP correspondent a book authored by the politician. A furious Japarov on Thursday accused Suvanaliyev of seizing the national security committee and claimed that Suvanaliyev had taken his government car and state guard away from him. He warned there could be clashes if the career policeman brought his own supporters to Bishkek. Jeenbekov's office said that the president had held talks with Myktybek Abdyldayev, who was elected speaker at the same session where Japarov was put forward. Abdyldayev's supporters had surrounded the hotel in what some saw as a bid to intimidate lawmakers, and opposition parties who drove protests against the vote results view the parliamentary session as illegitimate. They have put forward their own candidates for prime minister. As of Thursday, candidates from self-styled opposition parties claimed to control the state prosecutor's office, the national security committee and the interior ministry. Jeenbekov's office said he discussed a range of issues including government appointments with Abdyldayev, in a bid to restore stability. It was unclear whether he recognised Japarov's claim to the premiership. Japarov, a headstrong nationalist known for his opposition to the Canadian company operating Kyrgyzstan's largest gold mine, has told supporters that Jeenbekov had informed him he planned to resign. But the president's office said that "Jeenbekov once more reiterated that he is the legitimate president". The night of tumult that saw Japarov freed from jail also saw ex-president Almazbek Atambayev and several of his allies released as protesters seized government buildings and stormed into penitentiary facilities. Supporters of Atambayev -- a former ally turned foe of Jeenbekov -- said that they planned to hold a rally on Friday, and called citizens to "prevent the helpers" of Jeenbekov and his family coming to power. tol-cr/as/tgb
