At least 18 people were killed and 30 injured in further sectarian violence in northwestern Pakistan, officials said on Saturday, as tensions remained high following attacks on transport convoys that killed dozens of civilians this week, Reuters reported.

The latest killings in a tribal district began on Friday night, when armed men attacked a village in the district, said the chief secretary of the Khyber Pakhtunkhwa province, Nadeem Aslam Chaudhry.

"They set on fire petrol stations and damaged properties as part of revenge," he told Reuters by phone. He said he and top police officials would be visiting the area and engage tribal elders on both sides to restore order.

The toll since Thursday is 58 dead, read the report.

AFP reported on Saturday that 32 people were killed in the latest violence, citing an unnamed official.

On Thursday unidentified gunmen opened fire on passenger vehicles, killing over 40 in the Kurrram district, where armed Shia and Sunni Muslims have engaged in tribal and sectarian rivalry for decades over a land dispute near the Afghanistan border.

Most of the dead were Shiites, officials said, sparking retaliatory attacks by armed groups, with markets and schools remaining shut in a curfew-like situation, Reuters reported.

A police official requesting anonymity told Reuters that the death toll from the fresh violence could have been higher had residents of the village that was attacked not already evacuated their homes in anticipation of more violence.

He said the residents of Bagan village, a mostly Sunni area, had already left their homes and shifted to safe places in Lower Kurram.

A gunman was dead and three policemen injured after a shooting near the Israeli embassy in neighbouring Jordan, a security source and state media said on Sunday.

Police shot a gunman who had fired at a police patrol in the Rabiah neighbourhood of Amman, state news agency Petra reported, citing public security, adding investigations were ongoing, Reuters reported.

Jordanian police had earlier cordoned off an area near the heavily policed embassy after gunshots were heard, witnesses said. Two witnesses said police and ambulances rushed to the Rabiah neighbourhood, where the embassy is located.

The area is a flashpoint for frequent demonstrations against Israel. The kingdom has witnessed some of the biggest peaceful rallies across the region as anti-Israel sentiment runs high over the war in Gaza.

Police had called on residents to stay in their homes as security personnel searched for the culprits, a security source said.

Many of Jordan’s 12 million citizens are of Palestinian origin, they or their parents having been expelled or fled to Jordan in the fighting that accompanied the creation of Israel in 1948. Many have family ties on the Israeli side of the Jordan River, read the report.

Jordan's peace treaty with Israel is unpopular among many citizens who see normalisation of relations as betraying the rights of their Palestinian compatriots.
