American University in Afghanistan currently under attack, lecturers and students take cover

A militant attack is taking place at the American University in the Afghan capital, Kabul.

A large explosion has been heard and frightened students barricaded inside rooms in the building say they can hear gunfire close by.

At least one person has died and at least 12 are injured, officials say.

Police have described the attack, which began at about 19:00 local time (14:30 GMT), as "complex" and have deployed special forces.

The university president, Mark English, told AP news agency that a militant attack was underway and "we are trying to assess the situation".

An interior ministry official said he thought several gunmen, some with suicide vests, were involved.
