Kayani called on Gilani at the Prime Minister's House and discussed matters of national importance, state-run APP news agency reported without giving details.

Pakistani authorities had on Tuesday launched a crackdown on rights activists, lawyers and opposition party activists in Islamabad [Images] and Punjab province ahead of a "long march" by the lawyers' movement to pressure the government to reinstate judges sacked during the 2007 emergency by former President Pervez Musharraf [Images].

Hundreds of people have been detained or placed under house arrest by the authorities, who have banned protests and rallies across Punjab and Sindh provinces.
