At least 19 people have been killed and more than fifty wounded in a series of suicide attacks on government buildings in Kabul.
In one attack, two suicide bombers detonated devices in prison offices.
Afghan security sources report shooting two would-be suicide bombers in the capital’s justice ministry, while a third is thought to have escaped.
In a separate incident, at least one person was killed when security forces exchanged fire while chasing a group of insurgents next to the presidential palace.
The Taliban have claimed responsibility for the multiple attacks, saying they are revenge for the treatment of insurgents in Afghan prisons.
The blasts come a day before the new U.S. special envoy Richard Holbrooke is to visit the region.
