NI leaders postpone US trip to return to Belfast

The North's First and Deputy First Ministers have postponed a planned visit to the United States again today following the murder of a PSNI officer in Co Armagh last night.

Peter Robinson and Martin McGuinness had already postponed the trip after the murder of two British soldiers in Co Antrim on Sunday night.

They planned to fly out from London today to meet US businesses with investments in the North.

However, they have decided to return to Belfast instead to discuss the security crisis.

Mr Robinson and Mr McGuinness are still expected to travel to Washington next week for a St Patrick's Day meeting with President Barack Obama.
