text: The Taliban annual 'spring offensive' began today in Afghanistan with the jihadi group claiming responsibility for  108 attacks in the opening five hours. A US air base near Kabul and military outposts in Nuristan were targeted today as the militants continue to pursue territory in north east Afghanistan. According to the official spokesman for the Taliban, Zabiullah Mujahid, over 80 per cent of Afghanistan is currently 'controlled' by the Taliban. Whilst their figures are exaggerated, the Taliban's new offensive is set to the start of fresh violence in the troubled country. Taliban militants opened the offensive today with a failed rocket attack on a US base in Bagram air base, situated close to the Afghan capital city of Kabul. Taliban militants opened the offensive today with a failed rocket attack on a US base in Bagram air base, situated close to the Afghan capital city of Kabul. The rocket landed harmlessly in base and despite the Taliban claims that they had 'killed and wounded hundreds of Americans', no casualties have been reported. Improvised explosive devices (IEDs) were also reportedly detonated in Kunar and Khost province. Casualty numbers remain unconfirmed but the attacks symbolize a worrying indicator of the broad areas being targeted by the Taliban. The Taliban announced the launch of Operation Azm, meaning 'determination', on Wednesday, revealing fresh plans to target government buildings and Afghan security forces. The Taliban have been waging an jihadi insurgency since they were forced out of power in late 2001. With the emergence of ISIS, the Taliban are already facing a struggle for power in Afghanistan. The extremists want to turn Afghanistan into an Islamic Emirate, governed by strict sharia law. In December, photos emerged of a robber being publicly executed by Taliban fighters with machine guns. The Taliban announced the launch of Operation Azm, meaning 'determination', on Wednesday, revealing fresh plans to target government buildings and Afghan security forces in what is expected to be the bloodiest fighting season in a decade. With NATO forces pulling back from the frontlines, concerns remain whether trained Afghan forces will be able to consistently repel the expected barrage of Taliban attacks. 'The Islamic Emirate is going to launch the spring operations under the inspirational name of 'Azm' (Determination) at 5 am on 24th April 2015,' the Taliban said in a statement on Wednesday, using their official name. 'The main targets of these operations... will be the foreign occupiers, especially their permanent military bases... officials of the stooge regime, their military constellations, especially their intelligence, interior ministry and defence ministry officials.' Former Afghan Taliban fighters are seen holding weapons before they hand them over, as part of a government peace and reconciliation initiative, at a ceremony in Jalalabad recently. NATO's combat mission formally ended in December but a small follow-up foreign force has stayed on to train and support local security personnel. US President Barack Obama last month backpedaled on plans to shrink the US force in Afghanistan this year by nearly half, agreeing to keep the current level of 9,800 US troops until the end of 2015. The Taliban, who have waged a deadly insurgency since they were ousted from power in late 2001, said the announcement would damage any prospect of peace talks as they vowed to continue fighting. Aside from the Taliban, the Afghan government has also repeatedly warned of the Islamic State (IS) group making inroads into the country. President Ashraf Ghani blamed IS for a suicide attack last Saturday in the eastern city of Jalalabad that killed 33 people and wounded more than 100 others. If verified, that would mark the first major attack by the jihadists in the country.

Afghan security forces are struggling to cope with the new offensive across Afghanistan  particularly with the gradual withdrawal of NATO forces . The upsurge in attacks has taken a heavy toll on ordinary Afghans. According to the United Nations Assistance Mission in Afghanistan (UNAMA), the number of civilians killed and wounded up by 22 percent in 2014 compared to the previous year. In the first three months of 2015, civilian casualties from ground fighting were up eight percent on the same period last year, a new UNAMA report said. But in their statement, the Taliban said their 'top priority will be given to safeguard and protect the lives and properties of the civilian people' during the offensive.
