Trouble in Northern Ireland's capital Belfast for the second consecutive night as police clash with pro-British loyalists.<br/> <br />Nine officers were injured and 18 people arrested as up to 300 protesters reportedly hurled petrol bombs, fireworks and stones.<br/> <br />The violence comes a day after 10 police officers were injured during another demonstration, also in East Belfast, following a decision to reduce the number of days the Union Flag is flown from Belfast City Hall.<br/> <br />That decision a month ago, after a vote by mostly nationalist pro-Irish councillors, prompted the most sustained violence in the city in years.<br/> <br />Anti-British Catholic dissident groups have so far not joined in the flag protests, however, limiting the threat to Northern Ireland's 15-year-old peace.<br/> <br />Loyalists plan to hold another demonstration calling for reinstating the Union Flag outside City Hall on Saturday.
