Gordon Brown has condemned an attack on an army base in Northern Ireland which killed two soldiers.
Four other people were also injured when gunmen struck at Massereene army base in County Antrim, 16 miles north of Belfast, on Saturday night.
The prime minister described the attack as "evil" and said "no murderer" would derail the peace process.
No one has said they carried out the attack, but it is thought to be the work of dissident republicans.
The soldiers are the first to be murdered in Northern Ireland since Lance Bombardier Stephen Restorick was killed by an IRA sniper in 1997.
The dead men, both in their early 20s were due to fly to Afghanistan in the coming days.
'Shocked'
Mr Brown told the BBC: "I think the whole country is shocked and outraged at the evil and cowardly attacks on soldiers serving their country.
"We will do everything in our power to make sure that Northern Ireland is safe and secure and I assure you we will bring these murderers to justice.
