SINGAPORE, Aug 3 (Reuters) - The British band Massive Attack said its members were detained by Singapore police and "isolated and separately questioned" after the two performers raised a Palestinian flag at their concert in the city-state last Wednesday.

In a statement posted on Instagram on Sunday, the band said they were "surprised and disappointed" that the entire band was detained and questioned.

Several members had their hotel rooms searched and passports temporarily confiscated, the post said.

PESHAWAR/DERA ISMAIL KHAN, Pakistan, Aug 3 (Reuters) - At least 17 people were killed in a suspected suicide bombing outside a police station in northwestern Pakistan on Sunday, a rescue group and a regional police official said, as the country battles widening insurgencies.

The explosion took place in the Kabal area of Swat, a district in Pakistan's Khyber Pakhtunkhwa province.

A pro-police rally of local residents was taking place in the same area on Sunday, but it was not immediately clear whether the rally was the intended target.

CAIRO/JERUSALEM, Aug 2 (Reuters) - Israeli airstrikes hit Gaza for a second straight day on Sunday, killing at least 18 Palestinians, medics said, despite U.S. President Donald Trump's announcement of a breakthrough in efforts to implement last year's ceasefire agreement.

From dawn, Israeli warplanes hit Gaza City in the north, the central city of Deir al-Balah and the southern area of Khan Younis, causing the biggest daily death toll in weeks, according to Palestinian health officials.

US President Donald Trump said that new negotiations with Iran will begin Monday after he decided to hold off on striking the Islamic republic to pursue a deal to end the war entering its sixth month.

Trump told reporters on Sunday that the talks would cover the Strait of Hormuz –- a route for global energy supplies that has become a key sticking point in the conflict -- and ultimately, the denuclearization of Iran.

Dozens of Moroccans gathered on Sunday in the town of Fnideq, desperately seeking news of their loved ones who were among the thousands who swam across the nearby border to the Spanish territory of Ceuta this week.

Aldellatif, an agricultural worker in Moulay Bousselham, about 135 kilometres (84 miles) from Fnideq, feared for the fate of his 17-year-old brother, who ventured out with two friends in a bid to reach Ceuta by swimming.

CAIRO, Aug 2 (Reuters) - President Donald Trump has said the U.S. will hold off on a fresh attack on Iran as long as a deal can be reached quickly to halt Iran's nuclear ambitions and reopen the Strait of Hormuz.

Trump said late on Saturday on his Truth Social platform that Iran and other Middle Eastern countries had asked for time to complete a deal that would lead to "the Immediate, Complete and Total" reopening of the vital strait and "an end to Iran's nuclear threat".

Donald Trump has made some of the most aggressive public threats about military action of any modern US president. He has walked back many of them too. 

The 80-year-old Republican's comments about the US war against Iran have shifted, sometimes dramatically and quickly, since the conflict erupted on February 28.

He has repeatedly declared victory, claiming Iran's military capabilities were utterly defeated, only to later tweak the war timeline or threaten Tehran with more strikes. 

Saudi Arabia, Russia and five other key members of OPEC+ agreed in an online meeting Sunday to boost oil production by 188,000 barrels a day from September, against a backdrop of disruption caused by the Mideast war.

"The seven participating countries decided to implement a production adjustment of 188 thousand barrels per day," they said in a joint statement. 

The increase, decided by the key countries in the enlarged Organisation of the Petroleum Exporting Countries, was widely expected by analysts.

Iran on Sunday said it was nearing a deal with Oman over a new route through the Strait of Hormuz, hours after the US called off major strikes to allow for diplomacy.

US President Donald Trump said on Saturday that his country and Israel had agreed to hold off on new strikes on Iran, saying the "perimeters" of a deal were there.

The foes have been at war since February 28, when the US and Israel launched surprise strikes against Iran, though months of on-off diplomacy have led to periods of relative calm.
