DHAKA: Thousands of Pakistan’s anti-government protesters demanding resignation of prime minister Nawaz Sharif on Wednesday besieged the parliament building of Pakistan, trapping dozens of lawmakers inside.

Canada-based cleric Tahirul Qadri asked his supporters to guard all entry and exit points of the building and not let anyone move in or out of it until Sharif resigns.

Qadri and opposition leader Imran Khan have been leading separate protests for the past seven days to force Sharif’s resignation over alleged rigging in the 2013 elections.

Both protest leaders want a change of government through fresh polls.

‘It is time to besiege the parliament,’ Qadri said as he addressed his followers in front of the building, reports The Times of India.

‘You will not allow anyone to enter or leave [the building], not even a mosquito... not even the prime minister,’ the cleric said in his address.

Following the speech, hundreds of protesters wielding shields and sticks moved closer to the gates of the parliament and other buildings, ignoring warnings by police not to approach closer.

It is not known how many lawmakers are inside the building.

Sharif was also attending the session but there are reports that he safely left the building and reached his official residence.
