TEHRAN, Iran (AP) — The Latest on attacks in Iran's parliament building and the shrine of the Ayatollah Ruhollah Khomeini (all times local):

2 p.m.

The Islamic State group has claimed attacks on Iran's parliament and the shrine of Ayatollah Ruhollah Khomeini, which killed at least one person and wounded several others.

The claim was carried by the IS-run Aamaq news agency and circulated among the group's followers over social media.

The Sunni extremist group is at war with Iranian-backed groups in Syria and Iran and views Iran's Shiite majority as apostates deserving of death.

Iranian media says several attackers, including suicide bombers, took part in the assaults on both sites, with the parliament attack still underway. Lawmakers were in session at the time of the attack, and have been ordered to remain in place.

1:15 p.m.

Iranian state TV says one of the attackers taking part in an assault on parliament has blown himself up.

It says four attackers launched Wednesday's assault on parliament, which has wounded at least eight people. Police have surrounded the building, where a legislative session was underway, and heavy gunfire could be heard from outside.

A separate assault at the shrine of Ayatollah Ruhollah Khomeini, in another part of Tehran, killed a security guard and wounded four other people. It was not immediately clear who was behind the attacks or if they were coordinated.
