A suicide bomber killed at least nine police officers and injured several more in<a href="https://www.thenationalnews.com/tags/pakistan/" target="_blank"> Pakistan</a> on Monday. The police patrol was struck on a bridge in Kachhi, Balochistan province, in a presumed suicide bombing, although the exact nature of the attack has yet to be determined, police superintendent Mahmood Notezai confirmed to Pakistan<i>'</i>s<i> Dawn News.</i> No group immediately claimed responsibility for the attack, in which 13 others were wounded. It is the latest in a sharp rise in violence that has surged since November, when a ceasefire between the<a href="https://www.thenationalnews.com/world/2022/12/02/us-adds-pakistani-taliban-militant-group-to-terror-list/" target="_blank"> Pakistani Taliban </a>(TTP) and the government ended. The victims were returning from a week-long cattle show where they had been providing security, Mr Notezai told AFP<i>.</i> The suicide bomber travelled on a motorcycle and struck the lorry from behind, another police official told the agency. Attacks are not rare in the south-western province of Balochistan, which lies near the Afghan border and is home to a number of separatist groups waging guerrilla warfare against the government, including the outlawed<a href="https://www.thenationalnews.com/world/asia/balochistan-liberation-army-pakistan-hails-us-for-terrorist-group-designation-1.882355" target="_blank"> Balochistan Liberation Army.</a> Some Baloch groups say federal authorities are exploiting natural resources in the mineral-rich province. A child was among the victims of a <a href="https://www.thenationalnews.com/world/asia/2022/11/30/more-than-20-injured-in-pakistan-suicide-bombing/" target="_blank">suicide bombing</a> on a police patrol in the provincial capital of Quetta in November, later claimed by the TTP. The group often targets members of the security forces. It shares a hardline ideology similar to the Afghan Taliban but is a separate organisation. The TTP called for nationwide attacks after the end of the ceasefire, followed only two months later by a suicide bombing that <a href="https://www.thenationalnews.com/world/asia/2023/01/31/pakistan-mosque-blast-terror-attack-dead/" target="_blank">killed more than 100 people</a> in Peshawar. Police officers made up most of the victims of that attack, a rare breach of a highly fortified police compound in the city. Officials admitted a major security lapse had allowed the bomber to gain access to the compound before carrying out the attack in a mosque.
