Afghan Ministry of Interior Affairs Monday described trainings provided to police forces as inadequate.

Interior Ministry Spokesperson Zemarai Bashari said the ministry is making efforts to make sure Afghan police forces are sufficiently trained and equipped.

"Four-week or two-month trainings provided to police forces is not enough at all," Mr Bashari said.

Presently Afghanistan has an army that numbers at more than 150,000. President Karzai hopes to increase the forces to more than 200,000 by autumn this year.

Meanwhile, Nato has said there has been a huge shortage of trainers to make Afghan forces ready to take the lead in securing their country.

In a bid to speed up security transition, expected to begin this year from less restive provinces, Nato said some 740 additional trainers are needed.

The commander of Nato's training mission in Afghanistan, Lt Gen. William Caldwell, said the coalition wants to have the additional 740 trainers on the ground by this summer.

Afghan forces are expected to take security lead by 2014, the final target date for foreign troops gradual withdrawal that will begin in July 2011.
