More Pakistani officers held over Islamist links

Four majors serving in the Pakistan army are being questioned over links to the banned Islamist group, Hizb-ut-Tahrir.

The development followed an announcement on Tuesday that a brigadier had been arrested and was being interrogated over his alleged links to the organisation.

Brigadier Ali Khan, who was detained last month, was the highest-ranking serving officer to be arrested in a decade.

His family has said they have not heard from him for weeks. They insist that he is innocent of the allegations.
