QUETTA: In Pakistan's most dangerous province, lawyers are a crucial force for justice. So when a bomb decimated Balochistan's legal class this week, it left a vacuum that some say will never be filled. The mineral-rich province is plagued by roiling insurgencies, hit by regular militant attacks, and run by political leaders who are widely seen as corrupt.

Balochistan is the deadliest province in Pakistan for local journalists, according to Amnesty International, and foreign media are effectively barred. Lawyers are the only people shining a spotlight on the province's many problems.

The bomb, claimed by a faction of the Tehreek-i-Taliban Pakistan and the militant Islamic State group, tore through the crowd.

“We have lost the whole leadership,” said Attaullah Langov, a former secretary of the Balochistan Bar Association. The loss is a hole “that cannot be filled,” he told AFP.

Below are profiles of five victims who played a leading role in Balochistan's civic life:

Rights activist Sunghat Jamaldini

Sunghat Jamaldini was a member of the independent Human Rights Commission of Pakistan who had played an active role highlighting the plight of missing people in Balochistan.

Rights groups have accused the military of "disappearing" thousands of non-militant separatists, a charge routinely denied by army officials.

Jamaldini also fought for women's rights, an ongoing battle in deeply conservative and patriarchal Pakistan.

An active member of the bar association, he hailed from a political family, and was the son of Senator Jahanzaib Jamaldini of the Balochistan National Party.

'Dedicated' DawnNews cameraman Mahmoon Hamdard

Mehmood Khan, a cameraman for DawnNews, grew up in a slum outside Quetta, starting his career as a guard for a private security company where he was posted to the office of Dawn TV.

Fascinated by journalism, he badgered staff to join the editorial team, working his way up to the position of cameraman as he tried to finish his studies.

"He was very dedicated and committed," Syed Ali Shah, the DawnNews bureau chief in Quetta, told AFP.

"He vowed to become a reporter... Mehmood would have risen high in the profession, had he been given the opportunity to live."

Mehmood's older brother died several years ago and he married his widowed sister-in-law in order to care for her four children.

"He fathered three more children in the marriage," Shah said. "Everybody is worried about who will look after the widow and orphans now. Probably God."

Young reformist Adnan Kasi

Lawyer Adnan Kasi passed his bar exam in London in the early 2000s, becoming the youngest ever head of the Principal Law College in Quetta, where he introduced several reforms, including measures to combat nepotism and cheating.

He went on to found his own chambers and was practising in the Supreme Court.

Kasi was running for the position of secretary in the Baluchistan Bar Association elections, which were due to be held on August 13.

Anti-corruption vanguard Kakar

Lawyer Baz Mohammad Kakar was one of the first Baloch leaders of the lawyers movement to pledge his loyalty to former chief justice Iftikhar Chaudhry.

Chaudhry had become an unlikely hero as the figurehead of a 2007-2009 movement to restore judges deposed by former military ruler Pervez Musharraf in his bid to cling to power.

Kakar, a Supreme Court advocate, had spearheaded the movement in the province for two years.

Brother, friend, advocate Abdul Rasheed Khokhar

Abdul Rasheed Khokhar was a popular senior lawyer who was close friends with many in the lawyers movement against Musharraf.

The impact he had was aptly demonstrated by the crowd at his funeral beneath a scorching Balochistan sun Tuesday, where people from all walks of life travelled with relatives from outside the province to watch him be laid to rest.

His elder brother Abdul Hameed was desolate.

"What can I say about my brother?" he asked. "The whole city is gloomy over the loss of almost the entire leadership of the legal community."
