Three separate bomb attacks -- two in the capital Islamabad and one in a restive tribal region -- killed six soldiers and one civilian in Pakistan on Saturday.

Three separate bomb attacks -- two in the capital Islamabad and one in a restive tribal region -- killed six soldiers and one civilian in Pakistan on Saturday, officials said.

The explosions followed three days of intensive Pakistani military airstrikes against Taliban hideouts near the Afghan border, which killed at least 75 people.

There was no immediate claim of responsibility for the blasts but they come as the government is locked in stop-start peace talks with Tehreek-e-Taliban Pakistan (TTP), who have waged a seven-year insurgency in the country.

The first blast struck an up market shopping area close to the center of Islamabad around 2:00 am (2100 GMT Friday), killing a security guard and wounding another.

The second explosion came half an hour after the first, in a different part of the city.

The third bomb hit a convoy of paramilitary Frontier Corps in a remote village of the troubled Mohmand tribal district 150 kilometers (miles) northwest of Islamabad along the border with Afghanistan.

Six soldiers died and another was injured.

Thousands have been killed in militant violence in recent years but attacks on the capital, much of which is heavily guarded, have been rare.

Peace talks between TTP and the government began in February but have made little progress. A month-long ceasefire between Pakistan and the Taliban expired last month.
