UPDATE: TEHRAN, Iran (AP) – Iranian media says parliament siege over, 4 attackers killed.

___

TEHRAN, Iran – Several attackers stormed into Iran’s parliament and a suicide bomber targeted the shrine of Ayatollah Ruhollah Khomeini on Wednesday, killing a security guard and wounding 12 other people in rare twin attacks, with the shooting at the legislature still underway.

It was not immediately clear who was behind the attacks or if they were coordinated. The unusual attacks in Iran’s capital, Tehran, prompted the Interior Ministry to call for an urgent security meeting, according to the state-run IRNA news agency.

Iranian state media said police helicopters were circling over the parliament building and that all mobile phone lines from inside were disconnected. The semi-official ISNA news agency said all entrance and exit gates at parliament were closed and that lawmakers and reporters were ordered to remain in place inside the chamber, where a session had been in progress.
