Pakistan is not getting to the root causes of extremism, analysts have long warned
Pakistanis mourn after election rally bombing kills 128
Pakistan was in shock Saturday after a suicide blast killed 128 people, shaking confidence in security just as the dramatic arrest of ex-prime minister Nawaz Sharif ratcheted political tensions higher ahead of nationwide polls.
Sharif's dramatic return from London and subsequent arrest for corruption was overshadowed as the carnage in Mastung, in the country's southwestern province of Balochistan, unfolded late Friday.
Newspapers branded the blast – one of the deadliest in Pakistan's history – a "massacre", as analysts and media called on the military to, in the words of the daily Dawn, "do the job they are meant to do – ie preventing attacks".
One week ago, Sharif was sentenced in abstentia to 10 years in prison on corruption charges. He was transferred to the garrison city of Rawalpindi, adjacent to Islamabad, after landing in Lahore Friday. Media reports said he was being held in a prison there.
Sharif has claimed he is the victim of a military conspiracy, and there are widespread allegations from the media, politicians and analysts that the powerful security establishment is meddling in the polls.
Mobile signals were blocked and police deployed in the eastern city of Lahore where Sharif's supporters had gathered as he landed on Friday. Soon after, the scale of the destruction in Mastung, hundreds of kilometres to the southwest, began to emerge.
"It has never been more true that Pakistan's security establishment needs to focus on security, not politics," tweeted analyst Mosharraf Zaidi as mourners gathered to bury their dead in Mastung Saturday. More funerals were planned for the afternoon.
Hospitals in the area have been placed under "emergency" management after being overwhelmed in the hours after the attack, with around 150 also injured in the blast – many of them still in critical condition after suffering head trauma.
"I could hear voices screaming. I tried to get up and I saw people trying to run towards the gate. They were trampling over dead bodies," survivor Rustam Raisani told AFP from his hospital bed about the moments following the attack.
"We have imposed emergency [management] in the hospitals and cancelled the vacations of the doctors and paramedics," Balochistan home minister Agha Umar Bungalzai told AFP.
The provincial home secretary Haider Shako added that extra security forces had been deployed in "sensitive areas" and warned politicians to remain "vigilant".
A caretaker government has been installed ahead of the July 25 election, and prime minister Nasirul Mulk declared Sunday would be a day of mourning.
The attack was by far the deadliest of a series of blasts at various campaign events this week that have killed at least 154 people, including two local politicians, and underscored ongoing security challenges following years of optimism.
Security analyst Rahimullah Yusufzai termed the blasts a "wave of terror" that indicated coordination between militant groups, and noted that security forces could not protect every single campaign event.
But "they have been sidetracked," he added of the military, and "criticised for taking sides and focusing on politics".
He predicted the bloodshed would continue.
Violence has dropped significantly since the country's deadliest-ever militant attack, an assault on a school in the northwestern city of Peshawar in 2014 that left more than 150 people dead, mostly children.
The military intensified operations against militants in the tribal areas along the border with Afghanistan in the wake of that attack, and security has improved dramatically.
But analysts have long warned that Pakistan is not getting to the root causes of extremism, and that militants retain the ability to carry out spectacular attacks like the blast in Mastung.
"It has proved that the work that was required was not done," the head of the Pakistan Peoples Party, Bilawal Bhutto-Zardari, said in televised comments on Saturday, who warned that unless terrorism is wiped out "these incidents will continue to happen".
Lahore resident Shahzad Anwar told AFP on Saturday that such an attack was the result of the "failure of security institutions".
"It's wrong. It should not happen. The security institutions should work on this," he said.
Sharif's return is set to increase political tensions as his Pakistan Muslim League-Nawaz seeks to fend off a challenge from the party of cricketer-turned-politician Imran Khan at the polls.
Sharif has been banned from holding political office, but analysts have said his return is aimed at spiking support for his party, now led by younger brother Shahbaz, which is limping towards the vote after a lacklustre campaign.
Activists have called for candidates and the public to receive greater security protection as the polls draw closer.
The military has already warned of a security threat in the run-up to the vote, and said it will deploy more than 370,000 soldiers on polling day.
