Syria airstrikes UPDATES | Trump calls it 'perfectly executed strike'; UN Security Council rejects Russian attempt to condemn US aggression
As Trump announced actions against the Syrian government, explosions were heard in the Syrian capital Damascus, signalling a new chapter in a brutal seven-year-old civil war.
The US defense secretary rebuffed suggestions that the odds of war with North Korea had risen under Donald Trump's presidency.
The missile was fired into the Sea of Japan and flew for more than 900 km and reached a height of 4,000 km, which is the highest a North Korean missile has flown to date.
Jim Mattis said that the US supports solving the North Korean nuclear crisis diplomatically, after President Trump warned that 'time is quickly running out'.
Jim Mattis also warned Pakistan of global "diplomatic isolation" and losing its Non-NATO ally status if it failed to take action against terrorists.
Fighter jets, drone deals and shared concerns over Afghanistan's security challenges look set to dominate the agenda when Mattis visits India this week.
