Bulgarian lawmakers held on Wednesday a minute of silence to commemorate the attacks in Paris which killed 129 and wounded hundreds last week.

Parliament Speaker Tsetska Tsacheva opened the session saying there was "no justification" for such actions, and MPs were most decisively condemning any form of terrorism as an "unacceptable infringement on democracy and on the modern civilization."

Ataka, the nationalist party of Volen Siderov, was the single aprty that did not deliver a statement on the Paris attacks.

The main ruling GERB party pledged to fight against rising anti-migrant sentiment fueled by the latest developments.

Its deputy chair Tsvetan Tsvetanov extended condolence to the families of both victims of the incidents in Paris and the Sinai plane crash, a day after Russia announced it also believed a bomb had caused the aircraft to go down.

Nationalist Patriotic Front (PF) coalition, which backs GERB's minority government, for its part called on authorities to speed up the construction of a fence along the border with Turkey and to allow permanent army deployment to make sure troops provide assistance to border police.

Left-wing ABV party, which is part of the cabinet, called for sanctions against Russia to be revoked to allow Moscow a more prominent role in the regional security system, while opposition socialists demanded that the ministers of defense and foreign affairs be heard in Parliament to give an update on security issues in light of the attacks in Paris.
