A bomb detonated in an upscale shopping center in the Pakistani city of Lahore on Thursday has killed at least eight people and wounded 20 others, in the latest of a blitz of terror attacks to strike cities across the country.

With the bomber still at large, police kept people from entering or leaving the residential neighborhood after the explosion, which a Punjab police spokesman attributed to a 鈥減lanted bomb,鈥� either time- or remotely detonated, in an interview with Reuters.

The attack was the second in Lahore in two weeks, after a Feb. 13 explosion killed at least 13 people and wounded more than 80 others at a protest. Since then, suicide bombers claiming affiliation with multiple Islamic groups have also struck a courthouse in northwestern Pakistan and a famed Sufi shrine in the southern province of Sindh, with the total death toll reaching well over 100.

Those incidents have put the spotlight on the Pakistani government鈥檚 reaction 鈥� a nationwide paramilitary operation launched after the shrine bombing and aimed at聽鈥渋ndiscriminately eliminating residual latent threat of terrorism,鈥� as an Army spokesman put it, according to Voice of America. 聽

But the operation may also test聽Prime Minister Nawaz Sharif鈥檚 alliances with Islamist and right-wing parties, who have long opposed secular parties鈥� calls to deploy security forces in the province of Punjab, which will be the focal point of the operation. Mr. Sharif hails from there, and his younger brother is its chief minister. Several major Islamist parties allied with the Sharifs also have links to the thousands of hard-line religious seminaries based there and known for espousing militant viewpoints, although the parties themselves are not said to be involved in the latest attacks.聽

Pakistan鈥檚 war against Islamic militants has lasted more than a decade, intensifying in recent years after it broke off peace talks and launched offensives in the tribal regions near the Afghan border, which remains officially shut down because of security concerns.聽

Last October, Howard LaFranchi wrote for 海角大神, in an article about an Islamic-State-claimed attack on a police academy, that some experts link Pakistan鈥檚 current problems with terrorism to its longtime sheltering of similar-minded groups that carry out attacks on rival countries:

A year ago, Pakistani authorities were boasting about the success of the military鈥檚 campaign against militants. Terrorist attacks in Pakistan were down by half over the year before.

But now a fresh uptick in terrorist attacks ... has jolted the country anew.

The spike is raising fresh questions over whether Pakistan鈥檚 longtime support for militants that target India and Afghanistan is coming home to roost.聽And Monday鈥檚 attack is adding a new twist. With the so-called Islamic State claiming responsibility, some experts are wondering if Pakistan is revealing its vulnerability to the group鈥檚 desire to pit Sunni Muslims against Shiites. 聽

鈥淭he government is fighting terrorism, and certainly the US and many others are rooting for Pakistan to succeed in these efforts,鈥� says Lisa Curtis, a senior research fellow at the Heritage Foundation鈥檚 Asian Studies Center in Washington.

鈥淏ut at the same time the authorities have to recognize that part of the blowback from the years of tolerating and supporting the proxy groups operating in both Afghanistan and India is that you鈥檙e going to provide a conducive environment for other groups like this to operate in.鈥�

On Wednesday, Pakistan鈥檚 military said airstrikes in the border region killed several militants, while police officials in the southern city of Karachi said eight other Taliban-linked militants were killed in a raid.聽

US Ambassador to Pakistan David Hale also met with Pakistani foreign secretary Aizaz Ahmad Chaudhry and pledged that the United States would "continue to work in partnership with Pakistan to dismantle terrorist networks,鈥� according to the Associated Press.
