The Taliban's newly named top field commander purtportedly warned in a first public statement that Taliban fighters would continue their holy war until Western powers leave Afghanistan.
Violence struck throughout the country with two bomb blasts that killed four people, including a Finnish soldier in the usually quiet north, while NATO said it attacked a meeting of Taliban leaders in the south, killing an unspecified number of militants.
Shuhabuddin Athul, a Taliban spokesman, played an audio tape over the telephone to an Associated Press reporter that Athul said was a recording of Dadullah Mansoor, brother and replacement of Mullah Dadullah, the top Taliban commander shot to death in a U.S. operation this month in southern Afghanistan.
The man on the tape said Taliban fighters were ready to avenge his brother's death and would "pursue holy war until the occupying countries leave."
"They will pursue their attacks against occupying countries and the (Afghan) government," he said. "The number of suicide attackers is increasing. ... All of the Taliban, we are ready to carry out suicide attacks, roadside bombs and ambushes against the Americans and the government."
There was no way to verify that the voice was really Mansoor's.
Mullah Dadullah, a one-legged veteran who orchestrated an intensifying campaign of suicide attacks and beheadings, had long been one of Taliban leader Mullah Omar's top lieutenants. Al-Qaida's No. 2 leader, Ayman al-Zawahri, hailed Mullah Dadullah in a videotape released on Tuesday.
Athul has claimed that Mansoor was one of five prisoners released in March in exchange for kidnapped Italian journalist Daniele Mastrogiacomo. He was named as Mullah Dadullah's replacement last week, Athul said.
In a sign that the insurgency could be spreading, a bomb blast killed a Finnish soldier and an Afghan civilian in the northern town of Maymana, 100 meters (yards) outside a Norwegian-led base. Four Norwegian soldiers were lightly wounded.
The soldiers had been on their way to a hospital for the opening of a reconstruction project, said a Norwegian military spokesman.
Northern Afghanistan is relatively calm compared with the country's south and east, but has seen a run of attacks in recent weeks. A suicide bomber on Saturday killed 10 people in the northern city of Kunduz, including three German soldiers who were walking through a market.
"No parts of Afghanistan are safe, but the north has normally been quieter," said Oeglжnd. "But this is one of the threats we have been prepared for and have been aware of for a long time."
In the capital, Kabul, a suicide attacker on a motorbike blew himself up next to highway police guarding a road construction project, killing one policeman and a civilian, officials said.
An SUV carrying foreigners that had its window shattered in the attack may have been the intended target, said Gen. Ali Shah Paktiawal, the Kabul police director of criminal investigations. The SUV drove off and officials didn't know what group or country it was from.
NATO's International Security Assistance Force said "precision weapons" targeted a meeting of Taliban leaders on Tuesday in the southern province of Helmand. A military statement said "all of those who died were enemy insurgents," but did not indicate how many were killed, and Afghan officials said they were not aware of the attack.
In western Afghanistan, suspected Taliban militants beheaded a man and left his body in the Shindand bazaar in Herat province, said Mohammad Naieem, a border police official.
The man's head was placed on his chest along with a letter purportedly from the Taliban warning that anyone working with foreign military forces would be killed, Naieem said. The man was apparently taken Tuesday night and his body was discovered Wednesday.
In Khost province on Tuesday, a roadside bomb exploded as two trucks full of Afghan soldiers were driving by, killing four soldiers and destroying a truck, said Wazir Padshah, a provincial police spokesman.
Attacks in Afghanistan have increased in the last several weeks. More than 1,800 people have been killed in insurgency-related violence this year, according to an Associated Press count based on U.S., NATO and Afghan officials.
