'Few signs of progress' in Afghanistan: US inspector

Upbeat assessments of an improving security situation in Afghanistan do not line up with the facts on the ground, the Pentagon watchdog said Monday, pointing to 'few signs of progress' in the war-torn nation.

Top US officials and military commanders insist Afghan security forces are doing a better job of maintaining order, even though the Taliban are staging repeated attacks and the Islamic State group has conducted a series of high-profile suicide blasts.

'This quarter, US officials stated that the Taliban was not achieving its objectives and that momentum was shifting in favour of the Afghan National Defense and Security Forces (ANDSF),' the Inspector General of the Pentagon's office said.

'However, available metrics showed few signs of progress.'

The top US commander in Afghanistan, Gen John Nicholson, in November said the fight had 'turned the corner' and predicted that the Afghan security forces will expand government control of the population from about 64% now to 80% over two years.

But the inspector general said there had been 'little positive change' in the first quarter of 2018, with just 65% of the population living in areas under government control or influence.

At the same time, the number of Afghan security force personnel dropped from 331,708 to 313,728 -- a figure that is 11% below its authorised strength of 352,000.

'This shortfall, at a time when there is an increased emphasis on building the lethality of the ANDSF, renews concerns about recruiting, retention, and casualty rates of the ANDSF and the overall effectiveness of the ANDSF,' the report states.

President Donald Trump last year unveiled a much-vaunted 'South Asia Strategy' to tackle Afghanistan by including a broader regional approach.

The aim is to convince the Taliban through diplomatic, military and social pressure it cannot win and must reconcile.

'During this quarter there was little publicly available evidence that the actions to increase pressure on the Taliban were having a significant impact,' the report notes.

Much of the diplomatic pressure relies on Pakistan to eliminate Taliban safe havens, but despite suspending between $1.5 billion and $2 billion in planned security aid, Pakistan did not take any 'significant action' to eliminate the sanctuaries, the report said.

In February, the Afghan government offered the Taliban the chance to start a reconciliation process with no preconditions, and the US has suggested Taliban elements want to negotiate.

But attacks have continued unabated and last week the Taliban tried to seize the western city of Farah.

On Monday, the Taliban warned Kabul residents to avoid 'military centres' in the heavily fortified city, saying they are planning more attacks in the Afghan capital.
