JOHANNESBURG, South Africa — As gunshots rang out across a port town in northeastern Mozambique on Friday afternoon, nearly 200 people sheltering inside the Amarula Palma hotel confronted a devastating reality: The armed insurgents outside the hotel’s doors had all but taken control of the town and there was no one coming to save them any time soon.
For two days, hundreds of insurgents in the gas-rich region had been laying siege to the coastal town of Palma, firing indiscriminately at civilians, hunting down government officials and setting buildings ablaze as security forces tried in vain to repel them.
The violence sent thousands of people fleeing, with some rushing to the beach, where a ragtag fleet of cargo ships, tugboats and fishing vessels was ferrying people to safety.
But at the hotel, with daylight hours dwindling, the local residents and foreign gas workers who remained faced an impossible choice: Either wait inside, defenseless, for a promised evacuation in the morning, or try to make it to the beach.
campaign of violence the militants have unleashed. Insurgents have beheaded civilians in summary executions and left homes, schools and health centers destroyed.
Many analysts say that the insurgency is a home grown-crisis and that the group only maintains loose ties to the Islamic State. Still, the jihadist rallying cry has provided a banner under which mostly impoverished people angry about an array of local grievances can coalesce. It has also inspired the use of the international terrorist network’s brutal tactics.
Few journalists and human rights investigators have been able to report firsthand on the conflict from Mozambique, where government forces and private security contractors have also been implicated in abuses against civilians. And as the attack on Palma unfolded last week, phone lines and other communications in the town were cut by insurgents.

The Mozambique government guaranteed Total that it would secure the development, and Total said it would not hire private security companies like the Dyck Advisory Group, which was recently implicated in a report by Amnesty International of killing civilians.
“This attack is arguably the most significant yet, given that foreigners also came under the cross hairs of insurgents and because Palma is the gateway to the gas megaprojects,” said Dino Mahtani, deputy director of the Africa program at the International Crisis Group, who recently visited Mozambique. “It will lead to more pressure on Mozambique for hard military responses, perhaps at the expense of other policies that should still be on the table.”
Earlier this month, the United States formally designated the insurgency, known locally as Al-Sunna wa Jama’a, as a global terrorist entity after the group became identified with the Islamic State’s Central Africa Province in 2019.

By Friday morning the usually serene Amarula Palma Hotel, a sprawling compound with an outdoor bar and thatched-roof awnings that caters to foreign workers from countries like South Africa and the United Kingdom, had transformed into a chaotic epicenter of the crisis. By midday insurgents had surrounded the hotel and attacked, breaching its perimeter.
Helicopters operated by the private South African security company managed to evacuate 22 people. But with both fuel supplies and the light dwindling, contractors told the roughly 180 people who remained that they would not be able to fly them out until the following morning.
Dozens of people decided to chance an escape by road in the convoy that was ambushed.
On Saturday morning, the South African-operated helicopters evacuated around 20 more people who had remained in the hotel. Several others who had escaped the town and hid in the surrounding bush were also rescued by helicopters. Some had flagged the helicopters by writing out S.O.S. messages in stones, according to Mr. Dyck.
At the same time, a convoy of at least 10 vessels sailed into the bay of Palma in an informal effort to evacuate people, according to the ship-tracking website MarineTraffic.com.
A passenger ferry that usually operates along the coast of neighboring Tanzania also docked in Palma on Saturday and arrived in Pemba the following day, according to ship-tracking data, satellite imagery and photographs shared on social media. Local sailors on traditional wooden sailing boats, known as dhows, also carried some displaced people to Pemba, according to humanitarian workers.
While some of the fleet’s efforts were successful, other boats that attempted to come ashore to rescue people were forced to pull back when militants opened fire with small arms and mortars, according to American officials. At least one American citizen was at the gas project site near Palma during the attack, but was safely evacuated to Pemba, according to a U.S. official.
On Sunday morning, Mozambique Special Forces units launched an operation to reclaim the town. But by Sunday night, militants still held much of Palma, including the harbor, the officials said.
One British citizen who was part of the convoy who worked at RA International, a contracting company headquartered in Dubai, was missing as of Sunday night, according to an executive at the company.
At least one South African, Adrian Nel, 40, was killed in the ambush on the convoy.
Mr. Nel had been in Palma working at his family’s construction consulting company alongside his brother Wesley Nel, 37, and their stepfather, Gregory Knox, 55, who were also caught in the ambush. The two men managed to escape to the nearby forest and hid until private security contractors evacuated them by helicopter the following morning.
“They spent the night in the bush, with Adrian’s body,” Mr. Nel’s mother, Meryl Knox, 59, said in an interview. Ms. Knox spoke with her husband on Wednesday as the attack unfolded and the private security contractors who rescued the men by helicopter on Saturday.
“The insurgents had surrounded the hotel and there was no help from the Mozambican army,” Ms. Knox said. “These guys were just left on their own.”
