Carrying banners criticizing Armenia's illegal actions, a great number of Washingtonian protesters gathered on Thursday in front of the US Capitol building to condemn the deadly Armenian attacks on the Azerbaijani civilian settlements amid the border clashes over the Erivan-occupied Upper Karabakh region. Nearly 200 people gathered outside the US Capitol building in Washington on Wednesday to protest Armenia's attacks on Azerbaijani territories and occupation of Nagorno-Karabakh. The protesters, carrying Azerbaijani and Turkish flags, as well as banners criticizing Armenia's actions, shouted slogans in favor of Baku in front of the White House. They urged the US administration to put an end to Armenia's occupation and attacks on civilians. The protesters then headed to Turkey's embassy in Washington DC to convey their thanks for Turkey's solidarity with Azerbaijan. Embassy officials welcomed the protesters and reiterated Turkey's support for Azerbaijan. Clashes began on Sept. 27 when Armenian forces targeted civilian Azerbaijani settlements and military positions in the region, leading to casualties. Relations between the two former Soviet republics have been tense since 1991 when the Armenian military occupied Upper Karabakh. The OSCE Minsk Group -- co-chaired by France, Russia, and the US -- was formed in 1992 to find a peaceful solution to the conflict, but to no avail. A cease-fire, however, was agreed to in 1994.
