Two separate bomb attacks targeting security forces in Pakistan killed 19 people on Friday, officials said, the latest violence to hit peace talks between the government and Taliban militants.

A suicide attack in the suburbs of the northwestern city of Peshawar, close to the lawless tribal areas that are a haven for Taliban and Al-Qaeda linked militants, was followed a few hours later by a bombing in the southwestern city of Quetta.

Dialogue aimed at ending the Islamists' seven-year insurgency, which has claimed thousands of lives, resumed last week with government negotiators saying the process was ready to move to a new phase.

But a ceasefire declared by the Pakistani Taliban on March 1 has been shaken by several bloody episodes, including a major attack on a court complex in Islamabad that left 11 people dead.

The main Tehreek-e-Taliban Pakistan (TTP) faction denied that attack, which was claimed by a splinter group, but it nevertheless prompted many observers to question the militants' commitment to dialogue.

Friday's attack in Sarband village on the edge of Peshawar, close to the Khyber tribal district, came as Taliban negotiators met the TTP leadership to discuss the next steps in the talks process.

Taliban sources told AFP the TTP's ruling council had asked for the military to pull out of South Waziristan tribal area to allow talks to be held there.

The target of the Peshawar blast was a police armoured personnel carrier, officers said.

"It was a suicide attack and the bomber approached the police vehicle on foot," Najeeb-ur-Rahman, a senior police officer, told AFP, adding that nine people were killed.

Mohammad Faisal, another police officer, confirmed the attack and death toll.

In Quetta, a bicycle bomb containing eight to 10 kilos of explosives, apparently targeting a passing vehicle carrying security forces, killed 10 people and wounded 31, city police chief Abdul Razzaq Cheema said.

The city is the capital of the southwestern province of Baluchistan, which is rife with separatist and Islamist militants and plagued by sectarian bloodshed.

Friday's attack was the deadliest attack to hit the province since January 22, when a bomb targeting a bus carrying Shiite pilgrims returning from Iran killed 24 people.
