Kamal made the comment after attending a programme at Shishu Academy in the capital on Sunday when media persons asked him why the duo was not arrested yet.
He said: “I will not say that there is no development in this regard. We are chasing them and they can be arrested anytime. The main thing is people have stood against the militancy.”
He also said militancy was a global issue and sometimes the militants tried to expose their presence in the country.
“They are under control because of the stern actions of our law enforcing agencies,” said the home minister.
Marjan coordinated the Holey Artisan attack, while Zia had a hand in the targeted killings.
