Crunch talks for Pakistan leaders
Senior politicians are due to meet in Pakistan to try to resolve disputes which threaten to break up the coalition government.
Former Prime Minister Nawaz Sharif has said his party will pull out, unless judges sacked by ex-President Pervez Musharraf are immediately reinstated.
The other disagreement is over who should succeed Mr Musharraf, following his resignation on Monday.
The talks come a day after more than 60 people died in twin suicide attacks.
The party leaders failed to hammer out a deal when they met on Monday and Tuesday.
