QUETTA, Pakistan (AP) — A major earthquake rocked Pakistan's southwest Saturday, killing at least 15 and sending panicked people running into the street just days after another quake in the same region killed hundreds, officials said.
The U.S. Geological Survey said on its website that a 6.8 magnitude quake was felt in Pakistan's southwestern Baluchistan province.
Pakistan's Meteorological Department measured the earthquake at 7.2 magnitude, saying its epicenter was about 150 kilometers (90 miles) west of the town of Khuzdar.
Baluchistan government spokesman Jan Mohammad Buledi said those killed Saturday died in the Mushkay area of Awaran. The death toll from Tuesday's disaster was 359, he added.
Little may have been left to damage after Tuesday's disaster. Few of the mud and homemade brick houses in the area survived the 7.7 magnitude quake that leveled villages and buried people in the rubble. Since then tens of thousands of people have been sleeping under the open sky or in tents.
Chief Pakistani meteorologist Arif Mahmood told Pakistani television that Saturday's earthquake was an aftershock and such tremors could continue for weeks.
Pakistan television showed people at the main hospital in Awaran district fleeing into the street. In the provincial capital of Quetta, the tremor was so strong it prompted members of the local parliament to evacuate the building.
Baluchistan is Pakistan's largest but least populated province. The rough terrain and the lack of decent roads have made access difficult for rescue staff. The Pakistani Air Force has been air dropping supplies and using helicopters to ferry injured people.
But the Pakistani military has also been targeted by separatists operating in the region. The military has been trying to suppress an uprising in the vast, arid province for years by rebels who want an independent state for the Baluch people.
In the latest attack, gunmen Saturday killed four Pakistani troops carrying rations for earthquake victims.
The Frontier Corps troops were near the town of Panjgore, 480 miles (800 kilometers) south of Quetta, when their convoy was attacked, said a Pakistani military official on condition of anonymity because he was not authorized to speak to the media. Three troops were also wounded.
To the north, Pakistan is dealing with militants who want to overthrow the central government and establish a hard-line Islamic state.
Newly-elected Prime Minister Nawaz Sharif has vowed to pursue peace talks with the militants. But the militants have given little indication they are interested in negotiations. They initially rejected talks with the government and later demanded Islamabad release prisoners and begin withdrawing troops from the group's tribal sanctuary before talks could begin. Recent attacks have also called into question their interest in negotiating.
On Saturday, a spokesman for the Tehreek-e-Taliban criticized Sharif, saying his government is not serious about peace talks. The spokesman, Shahidullah Shahid, did not explicitly reject the offer but his words gave little room for negotiations.
The comments appeared to have been sparked by an interview Sharif made with the Wall Street Journal during a trip to New York, in which he said militants must lay down their arms and follow the constitution. Previously Sharif had not given preconditions for the talks.
"By telling us that we will have to lay down arms and respect the constitution, the prime minister, Nawaz Sharif, showed that he is following the policy of America and its allies," the spokesman said. "We will hold talks with (the government) only when it gets the real power to take decisions."
