Greece's Citizens' Protection Minister Christos Papoutsis was meeting with Prime Minister Lucas Papademos on Monday in the wake of extensive rioting in the center of Athens during a crucial Parliament vote on a second bailout loan for the country.

The meeting between the two men was scheduled for 3 p.m., reports said Monday.

Papoutsis has come under fire after police failed to contain violence that saw a number of buildings torched and shops looted. There have been calls for the socialist minister to resign.

At least 45 buildings were burned -- including the neo-classical home to the Attikon cinema dating from 1870 -- while dozens of stores and cafes were smashed and looted, police said on Monday.

The rioting began ahead of a tense vote in Parliament on a fresh package of austerity measures requested by the European Union and the International Monetary Fund in exchange for a second bailout loan. Lawmakers approved the agreement in the early hours of Monday despite more than 40 PASOK and New Democracy deputies voting against the terms of the deal.
