April 20 (Reuters) - Pakistan is confident it can get Iran to attend talks with the United States, a senior Pakistani government official told Reuters on Monday.

"We have received a positive signal from Iran. Things are fluid but we are trying that they should be here when we start the talks tomorrow or a day after," the source said, speaking on condition of anonymity.

The source added Pakistan is actively engaged with Tehran and Washington as U.S. President Donald Trump's ceasefire deadline looms.
