Security was reinforced in Armenian capital Yerevan, as armed men seized a police station and hostages on Sunday (July 17). <br /> <br />The men were demanding Armenians take to the streets to press their demands for the release of opposition politicians they said had been jailed unfairly. <br /> <br />One of their main demands was to free Jirair Sefilian, an opposition politician whom the authorities have accused of plotting civil unrest. <br /> <br />Sefilian was jailed in June over allegations of illegally possessing weapons. <br /> <br />Armenia's security service said one policeman had been killed and two wounded in the violence, but that negotiations were underway to resolve the standoff peacefully. <br /> <br />Two hostages had been freed, it said. Armenian news agencies cited police sources as saying several hostages remained.
