BAGHDAD, Iraq (CNN) -- Insurgents Monday targeted key oil sites in Iraq, firing mortar rounds into an oil distribution center in northern Iraq and bombing a pipeline in a southern suburb of Baghdad, Iraqi officials said.
The attack on the oil distribution center triggered a massive fire that halted the flow of crude oil to Iraq's largest refinery, a Kirkuk police official said.
The attack happened around 6:30 p.m. (10:30 a.m. ET) in Baiji, which is about 15 miles (25 km) northwest of Kirkuk, the police official said.
Iraqi army and civil defense personnel were still on the scene hours later trying to put out the fire.
Smoke from the blaze could been seen from miles away.
The refinery in Baiji has a daily production level of about 8.5 million liters of gasoline, 7.5 million liters of diesel and 6.5 million liters of white oil.
The second attack -- a bomb planted beneath an oil pipeline in the al-Rashid district -- also started a fire at around 11 a.m., an official with Iraqi civil defense said, adding that the civil defense put out the fire in about 2 hours.
The pipeline carries crude oil from storage tanks near Latifiya, south of Baghdad, to the Dora refinery in the capital.
Further south, in Muqdadiya, gunmen Monday stormed a mobile phone store, killed the owner and planted explosives which later detonated as people gathered inside, killing four people and wounding 25 others, an official with Diyala Joint Coordination Center told CNN.
That attack happened at 5 p.m. (9 a.m. ET). Muqdadiya is about 25 miles (40 km) north of Baquba.
High stakes meetings
In the midst of the violence, Iraqi President Jalal Talabani traveled to Iran and President Bush began a trip that will take him to the Middle East and a meeting with Iraqi Prime Minister Nuri al-Maliki.
Talabani's meeting with Iranian President Mahmoud Ahmadinejad, originally scheduled for Saturday, was delayed when Iraq closed Baghdad International Airport and imposed a curfew after more than 200 people were killed Thursday in the capital's Shiite slum of Sadr City.
Police called it the single worst attack since the war began.
Joining Talabani on the Iran trip is Iraqi Foreign Minister Hoshyar Zebari as well as the ministers of oil, education, industry, science and technology and a number of Iraqi lawmakers, Talabani's office said.
Iraq's government and the Bush administration are under pressure to look beyond the country's borders to bring an end to the ongoing violence. (Watch why pressure is mounting on Bush and al-Maliki )
The United States has refused to negotiate with Iran and Syria about helping to bring stability to Iraq, accusing both Tehran and Damascus of aiding insurgent groups in Iraq.
But a draft report by the Iraq Study Group, which is considering Iraq strategy, urges an aggressive regional diplomatic initiative that includes direct talks with Iran and Syria, according to The New York Times on Monday.
Iraq restored diplomatic relations with Syria last week when Syrian Foreign Minister Walid Moallem visited Baghdad. Ties had been cut in 1982 when Damascus backed Iran in its war with Iraq.
On Sunday, Iran's president said his country was willing to take a more active role in Iraq's future.
Ahmadinejad offered to help the United States "put an end to the present situation" in Iraq, on the condition that Washington stop its "bullying" there and revise its approach in the Middle East.
Meanwhile, Bush is scheduled to talk with al-Maliki in Amman, Jordan, on Wednesday and Thursday, following a NATO meeting in Latvia. (Full story)
Both al-Maliki and Bush face political pressure at home over the meeting and the future of Iraq.
On Friday, anti-U.S. Shiite cleric Muqtada al-Sadr's bloc threatened to withdraw support for al-Maliki if the meeting with Bush goes ahead as planned. (Watch show of force by al-Sadr's followers )
U.N. Secretary-General Kofi Annan said Monday he believes Iraq is "almost" in a civil war.
"I think given the developments on the ground, unless something is done drastically and urgently to arrest the deteriorating situation, we could be there, and in fact we are almost there," Annan told reporters. (Full story)
U.S. fighter jet crashes outside Baghdad
A U.S. Air Force F-16CG fighter jet crashed at 1:35 p.m. (5:35 a.m. ET) Monday outside Baghdad while making a "strafing run" -- firing on targets at a low altitude -- an American military official in Baghdad said.
The aircraft was carrying one pilot, but the military, which is investigating, would not disclose whether the pilot survived.
A Pentagon source said the plane was operating near Falluja, which is about 30 miles west of Baghdad.
Al-Jazeera TV aired video of what it said was smoldering wreckage of the F-16. The footage showed pieces of the aircraft, including the tail, which displays an aircraft number and an Air Combat Command logo.
