Thompson-Reuters correspondent Mirwais Harooni was among a group of reporters covering a press conference by Afghanistan President Hamid Karzai when explosions and gunfire sent them scrambling for shelter. Harooni live-tweeted the frightening experience.

Uh oh. Harooni says forces have their eye on the CIA compound.

Things seem to have settled down. Journalist Parwiz Shamal tweets that the Taliban has claimed responsibility for the attack.

Update:

Reuters reports at least 2 security guards were killed.
