And london. This is bbc world news. Its newsday. Its 8am in singapore, midnight in london and 7pm in washington, where the latest tweet from donald trump is grabbing attention around the world. The President Elect wrote that the United States must greatly strengthen and expand its nuclear capability. He said that process would continue until the world came to its senses. However, a spokesman has said mr trump was actually referring to the need to prevent nuclear proliferation. Our defence correspondent Jonathan Beale reports. America and russia still hold more than 90 of the worlds nuclear stockpiles, both able to deliver destruction on a massive scale, by ground, sea or air. For a quarter of a century, they have been reducing their nuclear arsenal. But the question now, is the arms race about to resume . Tonight, President Elect donald trump tweeted it caught many by surprise, including the obama administration. I cant speak for what the President Elects nuclear views, or his policy going forward. Thats for him and his team to speak to. What i can speak to is the approach that this administration has taken, to try to get us on a path to a World WithoutNuclear Weapons. President putin, too, has been ramping up the nuclear rhetoric. Today, addressing his military commanders, he talked of the need to strengthen russias Strategic Nuclear forces. Translation we can say with certainty that we are stronger now than any potential aggressor. Anyone. Both the United States and russia have made large cuts to their Nuclear Arsenals since the height of the cold war. But they still have many weapons. The us have stock piles of 7,000 warheads, of which 1,900 are deployed, or ready to use. Russia has just over 7,000, with just under 1,800 deployable. While the uk has 250 warheads, of which 120 are available to use, and could be fired from its vanguard submarines. Both america and russia are already modernising their Nuclear Weapons systems at significant cost. Whats not clear now is whether donald trump now wants to go much further. Tensions have been rising with russia, these us troops on exercise in the baltics a response to its intervention in ukraine. Russias Military Campaign in syria has deepened the rift. But donald trump has signalled he wants to improve relations with moscow, so his comments might be more directed at north korea, whose unpredictable leader boasts of now being a nuclear power, or even iran. Donald trump threatened to rip up a deal over its nuclear programme, still suspicious of irans intentions. What donald trump did with that tweet, was restart the nuclear arms race. Its notjust strengthen our nuclear arsenal, its expand our nuclear arsenal. We have Arms Control Agreements that limit, that reduce, that cap the weapons we deploy. He pays no heed to that, seems to want to bust through the cap. With Nuclear Weapons, words matter. Once again, a donald trump tweet has surprised, and raised plenty of questions.

Theres new pressure on the philippines outspoken president. The countrys independent Human Rights Watchdog is to investigate Rodrigo Duterte after he claimed to have killed several drug suspects personally. It follows a request for an inquiry by the united nations. Its no surprise that mr duterte has responded angrily, calling the un stupid idiots. Tom donkin reports. Philippines president Rodrigo Duterte was swept to power injune, on a promise to rid his country of Illegal Drugs and those who trafficked them. His critics argue he has authorised police, vigila ntes, and so called death squads to shoot suspected users and dealers on site. By his own admission, the president himself says he has personally killed. Earlier this week, the un cited that confession, calling for an independent Human Rights Group in the philippines to act and investigate mr duterte for murder. Theyve agreed, and will reopen an earlier investigation into the actions of the president. We are hoping with these new revelations and admissions we can further the investigation and ultimately have charges. Mr duterte has been unforgiving when discussing his methods. Recently he admitted to the bbc that he himself had killed drug suspects while he was mayor of the Southern City of davao. I killed about three of them. I dont really know how many bullets from my gun went inside their bodies, but it happened. As i said, i cannot lie about it. In his typically defiant style, he has responded to the investigation against him. While the many, and in some cases mysterious, recent killings in the philippines have alarmed leaders around the world, Rodrigo Duterte has vowed to continue his campaign as long as he is in power, knowing full well that for the moment, while he is president , his countrys constitution guards him from prosecution or punishment. Tom donkin, bbc news. The syrian army says its in complete control of aleppo after the last rebel fighters were evacuated.

When your mum was tweeting, was she tweeting your words or tweeting her words . Me and mum. Together . Yes. Her mother, fatima, insists the twitter account was banas idea, but admits it is a way to combat the regime. I think there now was a big fight out there. And i think our twitter was a weapon. Your twitter was a weapon . Yes. But the tweets attracted threats, and made it harderfor the family to join the Mass Evacuation of eastern aleppo. Fatima got bana on to one of the buses disguised as a boy. Today, the last opposition fighters retreated from their former stronghold, and by the evening the syrian army was in control of the entire city, for the first time in more than 11. 5 years. Just days after escaping all this, bana dreams of returning. Translation i was happy to leave, but sad at the same time. I wish i could go back to aleppo, go back home. I want to live in my house, because i love it, even if it had been bombed. I love my house. In english we shall overcome some day. Before saying goodbye, bana sang us a song about childhood and stolen freedoms.
