"Prime Minister Pashinyan arrived aboard the helicopter and was received by Karabakh’s top leadership," the source said.
According to the source, Pashinyan is expected to hold meetings with the unrecognized republic’s political and military leadership and a press conference in Karabakh’s capital of Stepanakert.
The parliament of Armenia elected opposition leader Pashinyan as the country’s new prime minister on Tuesday.
Pashinyan, who was the sole candidate for the prime minister’s seat, was elected by the majority of 59 votes in the parliament, while 42 votes were cast against his candidacy.
The predecessor of the new prime minister, Serzh Sargsyan, resigned earlier in the month amid mass protests of the opposition supporters across the country.
