Barack Obama to announce 250 more US personnel will be sent to Syria to tackle Isis

The US President Barack Obama is set to announce that Washington will send up to 250 military personnel to Syria to help tackle the threat of Isis. US officials said that the move would boost numbers of military personnel in Syria to around 300, although the White House would not comment.

Obama will make the announcement on Monday 25 April at the Hanover Messe fairgrounds in Germany during his farewell tour, CBS reports. In December 2015, he admitted that 50 elite US commandos had begun working inside Syria to tackle Isis.

Earlier on Sunday, Obama said that there would be no deployment of US ground troops in Syria and he did not see that Isis would be defeated in his last nine months as president.

He told the BBC: "It would be a mistake for the United States, or Great Britain... to send in ground troops and overthrow the Assad regime."

"I don't think there are any simple solutions. In order for us to solve the long-term problems in Syria, a military solution alone – and certainly us deploying ground troops – is not going to bring that about," he told the broadcaster.
