President Obama: U.S. will continue to be vigilant against terrorism

In light of the recent embassy closures, U.S. President Barack Obama said the U.S. would continue to be vigilant and go after known terrorists, the White House announced on Monday.

Obama made the remarks on Monday during a press conference at the White House. When asked if he still believed the core of terrorist organization al-Qaida was decimated, the President said al-Qaida was both reeling and dangerous.

"What I said in the same National Defense University speech back in May that I referred to earlier is that core al-Qaida is on its heels, has been decimated," Obama said. "But what I also said was that al-Qaida and other extremists have metastasized into regional groups that can pose significant dangers."

Obama said al-Qaida is less likely to be able to carry out massive homeland attacks like the September 11, 2001 terrorist attacks, but the terrorist organization could still go after embassies and be disrupting in areas where the security apparatus is weak.

"So it's entirely consistent to say that this tightly organized and relatively centralized al-Qaida that attacked us on 9/11 has been broken apart and is very weak and does not have a lot of operational capacity, and to say we still have these regional organizations like (Al-Qaida Arabian Peninsula) that can pose a threat, that can drive potentially a truck bomb into an embassy wall and can kill some people," Obama said.

The President said the U.S. must counteract terrorist threats by going after known terrorists carrying out plots. He said the U.S. would never completely eliminate terrorism, but it could weaken the terrorists while strengthening U.S. partnerships.

Obama would neither confirm nor deny drone strikes in Yemen.
