A car bombing outside a politician's home in central Pakistan has killed 22 people and wounded 70 others.
Tuesday's attack in Dera Ghazi Khan town in Punjab province is the latest in a series to hit Pakistan in recent months.
Islamist militants are blamed in the attacks.
Rescue official Natiq Hayat says the explosion left a large crater outside the house of Zulfikhar Khosa, the senior adviser to the chief minister of Punjab province.
No one in the house is believed to have been killed.
