The whereabouts of Kyrgyz President Sooronbay Jeenbekov is unknown, the Interfax News Agency reported on Thursday, citing the deputy head of the country's security council.

The official added that it was decided to close the country's border for security reasons.

Jeenbekov has not been seen in public since unrest began over Sunday's parliamentary vote, with the participation of 16 political parties. Preliminary results showed that four parties crossed the 7 percent threshold to enter the parliament. 

Some parties which failed to meet the voting threshold organized nationwide protests on Monday, demanding the election's annulment, claiming gross violations. 

Kyrgyzstan's Central Election Commission on Tuesday invalidated the results of the elections after clashes between police and protesters caused at least 590 injuries and one death.
