China on Wednesday strongly condemned the explosions in the southern Pakistani city of Karachi that killed 57 people and injured some 200.

"We express our deep condolences and sympathy to the families of the people killed and injured in the blast and voice our strong condemnation of the explosions," Chinese Foreign Ministry spokesman Liu Jianchao said.

Tuesday's blasts, the deadliest in Pakistan for years, occurred at a festival held to celebrate the anniversary of the birth of Prophet Hazrat Mohammad (Peace Be Upon Him).

A large number of people were taking part in evening prayers in Karachi's Nishtar Park when the bombs exploded near a wooden stage.

The attack targeted religious leaders, killing some of them. Police said that preliminary investigations revealed that there were at least two suicide bombers involved in the attack.

Sindh provincial government spokesman Salahuddin Haider said police have found parts of two bodies who are believed to be the suspected attackers.

The provincial government has announced a reward of 5 million rupees (about 83,333 U.S. dollars) to anyone who can provide information about the suicide bombers.

No-one has claimed responsibility for the explosion.
