ISLAMABAD: A high-level meeting summoned by Prime Minister Nawaz Sharif ended at the Prime Minister House, during which Imran Khan's demands were rejected and termed as 'illegal' and 'unconstitutional.'

The meeting was attended by key federal ministers and leaders of the Pakistan Muslim League - Nawaz (PML-N) and discussed the country's prevailing situation in context of sit-ins called by the Pakistan Tehreek-i-Insaf (PTI) and Pakistan Awami Tehreek (PAT).

After the meeting a spokesperson of the Prime Minister House said that "Imran Khan through his demands, which were unconstititional, wanted confrontation with the government."

The spokesperson severely criticised the 'civil disobedience movement' launched by the PTI chief and termed it as being against the state of Pakistan.

Credible sources told Dawn that Prime Minister Nawaz Sharif had instructed Federal Interior Minister Chaudhry Nisar Ali Khan to beef up security of key government installations situated in and around Constititional avenue in the federal capital city, which is now known as Red Zone area.

The federal interior minister was also advised that security of government installations should be ensured at all costs and those violating the law should be dealt with iron hands.
