Pentagon gives briefing on 'overwhelming' strikes

The Pentagon has given a press briefing on last night's strikes on Syrian chemical facilities. General Kenneth McKenzie described the strikes as "precise, overwhelming and effective". Here are some of the key points from the briefing:

• 105 weapons were launched against three targets in Syria, from US cruisers, submarines and bombers and from British and French jet aircraft and a French warship
• US Pentagon official says the strikes have "crippled" the Syrian chemical weapons programme and set it back "for years"
• There was no indication that Russia anti-air units were involved in targeting the missiles, General McKenzie said
• The US believes Syria fired 40 unguided anti-air missiles at US and allied cruise missiles but none were successfully shot down
• British Tornado bombers were escorted by RAF Eurofighter Typhoon jet aircraft
• The Pentagon has not seen any response from Syrian or Russian forces to the strikes
• But General McKenzie said they were "postured" for any retaliation, whether from the Syrian government or its allies
