The death toll has risen to at least 59 from an explosion at a religious gathering in Pakistan's southwestern province of Balochistan, after officials said more critically ill victims died in the hospital overnight.
Dozens more were injured in the attack that took place on September 29, when one or more suicide bombers are believed to have targeted a procession celebrating the birth of Prophet Muhammad in the Mastung district, some 60 kilometers from the provincial capital, Quetta.
It was one of the deadliest attacks on civilians in Pakistan in months and prompted officials to declare a state of emergency at Quetta area hospitals.
Police on September 30 filed a report to launch an investigation, saying they had sent DNA from the suicide bomber to be analyzed.
Pakistani Interior Minister Sarfaraz Bugti told reporters in Quetta that India's intelligence agency, the Research & Analysis Wing (RAW), was involved in the suicide attack but provided no details or evidence to support the claim.
Pakistani officials have long claimed that India sponsors violent groups in Pakistan. India has consistently denied the claims.
On the same day as the attack in Balochistan, at least five people were killed in explosions that targeted a mosque and a police station in the restive northwestern Khyber Pakhtuknkhwa Province bordering Afghanistan, according to police and media reports.
Dozens Killed During Two Attacks On Worshippers in Pakistan
The UN Security Council's members issued a statement in which they "condemned in the strongest terms the heinous and cowardly suicide terrorist attacks in Pakistan today that targeted a religious procession in Mastung, Balochistan Province, to commemorate 12 Rabi-ul-Awaal, the birthday of Prophet Muhammad, and a mosque in the Hangu district of Khyber Pakhtunkhwa province."
They "underlined the need to hold perpetrators, organizers, financiers, and sponsors of these reprehensible acts of terrorism accountable and bring them to justice."
Pakistani caretaker Prime Minister Anwar ul-Haq Kakar and President Arif Alvi along with cabinet ministers and other officials and religious leaders condemned the killings.
No group has claimed responsibility.
Dr. Rashid Mohammad Shahi, the head of the Mastung Health Department, told RFE/RL that more than 50 people were wounded in the Mastung incident at a celebration of what is known as Mawlid al-Nabi, during which Muslims usually hold gatherings and distribute free meals to the poor.
Balochistan, Pakistan's largest province that borders both Afghanistan and Iran, is regularly targeted by Islamist militants, sectarian groups, and nationalist separatists.
The most prominent militant group in the region, the outlawed Balochistan Liberation Army, or BLA, routinely takes credit for attacks on Pakistani security forces.
The BLC claims that ethnic Baluchis face extortion and discrimination by Pakistani authorities, a charge that Islamabad rejects.
