A suicide bomber struck at an army base in Pakistan's eastern Punjab province on Thursday, killing a soldier and injuring eight others, an army spokesman said.
The unidentified suicide bomber was also killed when he exploded himself near a group of soldiers undergoing training in Khrian, 130 km from Islamabad.
"The soldiers were conducting training when the bomber walked towards them and blew himself up," Major General Waheed Arshad said.
The injured were shifted to a military hospital in the city, he said adding, one of them was in critical condition.
The army was investigating to ascertain the bomber's identity, he said.
The area, which has a large army base, was cordoned off by police and journalists were not allowed to enter.
No one has claimed responsibility for today's attack, but authorities suspect 'elements' opposed to President Pervez Musharraf's joining the US-led coalition might be behind it.
Suicide bombers have targeted soldiers in Pakistan in recent months with attacks being carried out in North West Frontier Province and the tribal region.
But it is the first such assault against the army in Punjab. Over 42 Pakistani Army trainees were killed and 20 wounded in a suicide attack in a military camp in North West Frontier Province in November 2006. President Musharraf survived two attacks in 2003 which he blamed on extremists.
