Biden meets US troops in Iraq for Independence Day

US Vice President Joe Biden met US troops preparing to mark their Independence Day holiday on Saturday, on the third day of a visit he has used to urge Iraqi politicians to do more to reconcile rival factions.

Biden, who US President Barack Obama has asked to take a leading role in coordinating US Iraq policy, also presided over a naturalisation ceremony for 237 soldiers from 59 countries taking an oath of US citizenship. (Reuters)
