LONDON (AP) _ Police will install 26 sophisticated cameras in London's financial district to help defend against IRA bombers.

The cameras, set up in a one-square-mile area, will be able to distinguish vehicle registration numbers as well as the features of drivers and passengers, police Commissioner Owen Kelly said Tuesday.

The Irish Republican Army, which is fighting British rule in Northern Ireland, exploded a bomb in the district April 24 that killed one person and wounded 45. A year earlier, an IRA bomb in the same district killed three and injured 91.

The two bombs damaged more than 250 buildings at a cost of $2 billion.

In July, police closed 17 roads into the district and set up permanent checkpoints on the other eight.
