Donald Trump is the frontrunner in the Republican race to be the presidential nominee for next year's election. What are his policies and beliefs?
1. Arab-Americans cheered the attacks on 9/11.Trump repeatedly claimed that on 11 September, 2001, there were thousands of Arab-Americans celebrating in New Jersey after two planes flew into the Twin Towers. He says such public demonstrations "tell you something" about Muslims living in the US. However, there are no media reports to back up the claim.
2. There should be surveillance on US mosques.Trump believes Muslims should be tracked by law enforcement as a counterterrorism initiative. He has walked back some comments about keeping a database on all American Muslims, but says he doesn't care if watching mosques is seen as "politically incorrect".
3. The US should use waterboarding and other methods of "strong interrogation" in its fight against the Islamic State. The candidate said that these methods are "peanuts" compared to the tactics used by the militants, such as beheadings.
4. Trump would "bomb the hell" out of IS. He claims that no other candidate would be tougher on the Islamic State and he would weaken the militants by cutting off their access to oil.
