ISLAMABAD (REUTERS)- Pakistan's largest opposition party said on Tuesday (Nov 1) that two of its supporters have died from police use of tear gas to prevent hundreds of supporters from entering the capital, Islamabad, for a planned protest demanding the Prime Minister step down.

"Two of our workers have been killed due to excessive use of expired tear-gas shells," said Mr Shah Mehmood Qureshi, a senior leader of opposition party Pakistan Tehreek-e-Insaf (PTI) said on local Geo TV.

The local authorities could not immediately be reached to confirm any deaths.

Hundreds of supporters of the cricketer-turned-politician Imran Khan clashed with police overnight while trying to enter the capital for a planned citywide shutdown on Wednesday.
