Nikki Haley, United States ambassador to the United Nations, receives a note from an aide during an emergency meeting of the U.N. Security Council at United Nations headquarters, July 5, 2017 in New York CityImage copyrightGETTY IMAGES Image caption America's UN ambassador Nikki Haley says the US is prepared to defend itself and its allies The US has said that it will use its "considerable military forces" on North Korea "if we must". Describing the North's latest missile test as a sharp military escalation, the US ambassador to the United Nations said the US will table a new resolution against Pyongyang. Ambassador Nikki Haley also threatened to use trade restrictions. The missile launch, the latest in a series of tests, was in defiance of a ban by the UN Security Council. North Korea's test launch of an intercontinental ballistic missile (ICBM) on Tuesday was "quickly closing off the possibility of a diplomatic solution," Ms Haley said. "The United States is prepared to use the full range of our capabilities to defend ourselves, and our allies," the US ambassador told the UN Security Council, meeting for an emergency session to discuss the test. "One of our capabilities lies with our considerable military forces. We will use them, if we must, but we prefer not to have to go in that direction". The French ambassador told the council that France also favours a new resolution on North Korea, which would tighten sanctions. Is the new missile test a game-changer? Can the US defend itself against N Korea? Possible solutions to crisis Russia, which condemned the test, said the possibility of using military measures "should be excluded". China's representative said Beijing found North Korea's actions unacceptable. But he repeated China and Russia's joint call for the US to reverse plans to deploy an anti-missile system in South Korea, and for the two countries to suspend their joint military exercises close to North Korea. Both Russia and China are permanent members of the UN Security Council and could veto any new resolution. Earlier, Donald Trump criticised China for its trade with North Korea. Ms Haley, who said she had discussed the issue with the president, said the US could cut off trade with countries which continued to trade with North Korea in violation of UN resolutions. "We will look at any country that chooses to do business with this outlaw regime," she says. Jump media playerMedia player helpOut of media player. Press enter to return or tab to continue. Media captionWhy Trump only has bad North Korea options, as the BBC's Korea correspondent Steve Evans explains Mr Trump has arrived in Warsaw, ahead of his trip to Hamburg for the G20 summit of major economies, where he is due to meet Chinese President Xi Jinping for the second time. Why is Donald Trump going to Poland? The US president held talks with China's leader Xi Jinping at his Mar-a-Lago retreat in Florida in April. After those talks, Mr Trump hailed "tremendous progress" with China, but on Wednesday the US president tweeted: "So much for China working with us - but we had to give it a try!" North Korea's test of a long-range missile, which some experts think could travel far enough to hit Alaska, will be the subject of talks between leaders at the G20, which includes Russia. Grey line Why have US-China relations soured? Barbara Plett Usher, BBC state department correspondent There's little doubt the honeymoon between Donald Trump and Xi Jinping is over. The administration is frustrated that China isn't doing more to put the squeeze on North Korea. Beijing is angry about recent moves taken by the White House, including sanctions on a Chinese bank for doing "illicit" business with Pyongyang, and a $1.4 billion arms sale to Taiwan. In one way this tension is neither new nor surprising - previous American presidents encountered similar resistance from Beijing, which is determined to prevent chaotic upheaval in North Korea. But the stakes are higher because Pyongyang's nuclear weapons programme is becoming more of a threat. Mr Trump might respond by imposing more sanctions on Chinese banks and front companies that deal with North Korea. But some Asia experts say China would be readier to increase economic pressure on the regime if the US took up Beijing's push for negotiations to deal with the crisis. Grey line What has North Korea said? Tuesday's launch was North Korea's first-ever test launch of an intercontinental ballistic missile (ICBM). State news agency KCNA quoted leader Kim Jong-un as saying the test was a "gift" to the Americans on their independence day. The report warned of the possibility of more tests, saying he had ordered officials to "frequently send big and small 'gift packages' to the Yankees". Pyongyang said earlier the Hwasong-14 ICBM had reached an altitude of 2,802km (1,731 miles) and flew 933km for 39 minutes before hitting a target in the sea. Have North Korea's missile tests paid off? North Korea, it said, was now "a full-fledged nuclear power that has been possessed of the most powerful inter-continental ballistic rocket capable of hitting any part of the world". Grey line What is an ICBM? ICBM flight track A long-range missile usually designed to carry a nuclear warhead The minimum range is 5,500km (3,400 miles), although most fly about 10,000km or more Pyongyang has previously displayed two types of ICBMs: the KN-08, with a range of 11,500km, and the KN-14, with a range of 10,000km, but before 4 July had not claimed to have flight tested an ICBM. It is not clear what differentiates the Hwasong-14 North Korea's missile programme in detail Grey line What now for Washington? - Dr John Nilsson-Wright, Chatham House The intercontinental ballistic missile Hwasong-14 is seen during its test launch in this undated photo released by North Korea's Korean Central News Agency (KCNA) in Pyongyang, 4 July 2017Image copyrightKCNA Image caption North Korean media released this image of Tuesday's missile launch By bringing Alaska within range, the new missile test is an unambiguous game-changer in both symbolical and practical terms. US territory (albeit separate from the contiguous continental US) is now finally within Pyongyang's cross-hairs. For the first time a US president has to accept that the North poses a "real and present" danger not merely to north-east Asia and America's key allies - but to the US proper. President Trump's weakness lies in having overplayed his hand too publicly and too loudly.

An indefinite strike has paralysed life in India's tea-producing region of Darjeeling. A local party is demanding a separate state for the area's majority Nepali-speaking Gorkha community.

The protests have followed a recent decision by the West Bengal government to introduce Bengali as a compulsory subject in schools across the state, including in Darjeeling.

The Gorkha Janmukti Morcha or GJM (Gorkha People's Liberation Front), which is spearheading the protest, has threatened "a fight-to-the-finish" for Gorkhaland, the separate state they want carved out of West Bengal's northern hill region.

The strike began last month but was relaxed to allow shops to open during Ramadan, when Muslims fast during daylight.

The strike has disrupted public transport, causing inconvenience to thousands of local residents.

Darjeeling has been hit at the peak of the summer tourist season. Tens of thousands of visitors who were left stranded in the hills when the violence began in June have left.

The leader of the movement, Bimal Gurung, has been in hiding ever since he announced the strike. His supporters are accused of attacking policemen and intimidating shopkeepers to keep their shutters down.

The West Bengal police have raided his many offices and hideouts across the hills and arrested his supporters for burning down government offices and vehicles. Protesters have retaliated by burning effigies of Chief Minister Mamata Banerjee, who leads the Trinamool Congress party which governs the state.

In June, the army was called out to help police tackle the protesters. At least five people were killed and more than 100 others, including 30 policemen, injured in the violence.

Darjeeling saw violent protests for a separate state in the 1980s in which more than 1,200 people died.

That ended when the Gorkhas settled for an autonomous council that promised a degree of self rule for the hill region.

But the leader of the 1980s protests, former soldier Subhas Ghishing, has now been replaced by his former lieutenant, Mr Gurung, who is more hardline.

Long-time Darjeeling residents fear an uncertain future if the hostilities in India's tea bowl continue.
