A leading doctor at a clinic in Yerevan said Airikian, a candidate in Armenia's mid-February presidential election, was hospitalized with gunshot wounds late on Thursday. His condition was stable, according to Ara Minasian, the chief doctor at the capital's Clinical Hospital.
Armenian Shans TV quoted a police spokesman as saying that gunmen had fired two shots, wounding Airikian with a bullet to his shoulder, in the courtyard of his house in the center of the capital.
Airikian, 63, a former dissident, is the leader of a moderate opposition party, the National Self-determination Union.
President Sarkisian tipped for re-election
Latest opinion surveys had shown incumbent President Serge Sarkisian likely to win re-election. The wounded Airikian had previously only garnered a few percent.
The incident could, however, delay voting. Under Armenia's constitution, an election can be postponed by two weeks if a candidate is unable to campaign or run.
Armeniais a landlocked ex-Soviet republic of 3.2 million that is Russia's main ally in the South Caucasus. Its presidential election in 2008 was marred by violent clashes between opposition protesters and police.
Armeniahas a collective security agreement with Russia, while its oil-rich rival and neighbor Azerbaijan has a similar agreement with Turkey.
For decades the two countries have disputed the ownership of the Caucasus mountain region of Nagorno-Karabakh, which is controlled by ethnic Armenians. It broke away from Azerbaijan as the Soviet Union fell apart.
A war in the early 1990s claimed about 30,000 lives and ended in a ceasefire in 1994.
Last October, President Sarkisian accused Azerbaijan of contemplating a new war over the territory. Tensions were high after Hungary sent home to Azerbaijan an Azeri officer convicted of killing an Armenian officer on a NATO training course.
