KABUL: Senior Afghan Taliban figures met on Monday to agree on a successor to Mullah Akhtar Mansour, the leader of the movement who US President Barack Obama confirmed had been killed in an American air strike at the weekend. The Taliban have so far made no official statement on the fate of Mansour, who assumed the leadership only last year. But senior members have confirmed that their main shura, or leadership council, has been meeting to discuss the succession in a bid to prevent factional splits from fragmenting the movement. An undamaged Pakistani passport in the name of Wali Muhammad, which Pakistani authorities said contained a visa for Iran, was recovered next to the burned-out car at the scene of the attack and is believed to have belonged to Mansour. But it is unclear what he may have been doing in Iran and why he was apparently travelling in Pakistan without a security detail. A spokesman for the Iranian Foreign Ministry was quoted on state media denying that such an individual had crossed the border from Iran to Pakistan at the time in question. Obama has stressed that the operation against Mansour did not represent a shift in US strategy in Afghanistan or a return to active engagement in fighting, following the end of the international coalition’s main combat mission in 2014. The US currently has 9,800 troops in Afghanistan, divided between a NATO-led mission to train and advise local forces and a separate counterterrorism mission fighting militant groups such as Islamic State and al Qaeda. A decision is expected later this year on whether to stick with a timetable that would see the number of troops cut to 5,500 by the start of 2017. The Taliban, which have previously rejected ouvertures to join talks with President Ashraf Ghani’s government, have been pushing Afghan security forces hard since the launch of their spring offensive in April. The attack on Mansour has thrown the movement into disarray at least temporarily, but Afghan authorities have braced for an upsurge in violence as rival candidates position themselves to succeed him. Although some individual Taliban members have been quoted in media reports saying that Mansour was killed, the group’s leadership, keenly aware of the need to limit splits, has not issued its own confirmation. “The leadership is being very careful because one wrong step could divide the group into many parties,” one Taliban official from the eastern province of Nangarhar said, referring to guerrilla leaders who fought the Soviets in the 1980s before splitting into warring factions. Serious divisions emerged last year when it was confirmed that Mullah Mohammad Omar, the group’s founder, had been dead for two years, leaving his deputy Mansour in effective charge of the movement. One senior member of the shura said that the choice for the next leader appeared to be shaping around Mansour’s deputy, Sirajuddin Haqqani, or a member of the family of Mullah Omar, such as his son, Mullah Mohammad Yaqoob. “We prefer someone from Omar’s family to put an end to all internal problems,” he said.
