In this task, you are given an article. Your task is to summarize the article in a sentence.

Input: Consider Input: President Trump had said he was praying for the victims, but added that "states that sponsor terrorism risk falling victim to the evil they promote".
But Javad Zarif said Iran "rejected such claims of friendship" and claimed the attackers from so-called Islamic State had been "backed by US clients".
Thirteen people died in the attacks.
Gunmen and suicide bombers targeted parliament and the mausoleum of Islamic Republic founder Ayatollah Khomeini, in an unprecedented twin assault that lasted several hours on Wednesday morning.
Iran says the attackers, all of whom were killed, were Iranians who had joined IS. The militant group has threatened further assaults on Iranian Shia Muslims.
In an earlier tweet, Mr Zarif appeared to blame its regional rivals for the attack, saying: "Terror-sponsoring despots threaten to bring the fight to our homeland. Proxies attack what their masters despise most: the seat of democracy."
Sunni-ruled Saudi Arabia - a key US ally - and Shia-majority Iran back opposing sides in conflicts across the region.
The Saudi authorities have given money and weapons to hardline Islamist rebel factions seeking to overthrow Syrian President Bashar al-Assad - Iran's staunch ally. Saudi-based charities and individuals have also been accused of financing Sunni extremist groups across the region over the past two decades.
President Trump visited Saudi Arabia last month and made a speech blaming Iran for regional instability.
Iran's powerful Islamic Revolution Guards Corps (IRGC) have already accused Saudi Arabia and the US of being behind the attacks. Both countries have condemned the violence.
However, Iranian Supreme Leader Ayatollah Ali Khamenei has downplayed the attack's significance, saying terrorists "fumbling with firecrackers" would not "affect the will of our nation".
It comes amid heightened tensions in the Middle East, with Saudi Arabia and other Arab states cutting ties with Qatar over alleged support for Islamist militants in the region and closer ties with Iran.
Claiming the attack, IS posted a video which showed what it claimed was footage from inside the parliament building.
A voice is heard saying, in Arabic: "We're not going anywhere. We're staying forever."
BBC Persian's Jenny Norton says that despite Iran's active involvement in fighting IS in both Iraq and Syria, the Sunni group has not until now carried out any attacks inside Iran, and appears to have little support in this predominantly Shia country.
However, our analyst says, in recent months the group has stepped up its Farsi-language propaganda efforts - targeting Iran's restive Sunni minority.
Iranian intelligence agencies claim to have foiled a number of IS-inspired plots.
But by mounting a successful attack, IS could claim a major coup against a traditional foe that other Sunni jihadist groups, including its rival al-Qaeda, have failed to target in the past.
Middle East analyst Dina Esfandiary says one possible consequence will be increased calls by hardliners for tougher action against IS in Iraq and Syria.
Public support for action in Iraq is likely to grow, as it did when IS took swathes of territory in the country in 2014.
But Iran's involvement in Syria is not popular, our analyst says - it is seen as having few benefits and costing too many Iranian lives.
The attacks will also boost the popularity of the Revolutionary Guards, seen as protectors of the nation.

Output: Iran's foreign minister has denounced as "repugnant" a White House statement on Wednesday's terror attack in Tehran that said Iran was a "terror sponsor".


Input: Consider Input: The 30-year-old Russian's 15-month ban for using meldonium ends on Wednesday when she plays in the first round.
"You have to look at how other leagues and tours have handled players who have come back," Simon told BBC Sport.
"They come right back to the team and start playing."
Italy's Roberta Vinci  - Sharapova's opponent in her comeback match on Wednesday - disagrees with the decision to invite the five-time Grand Slam champion into the main draw.
World number eight Agnieszka Radwanska, who Sharapova might have met in the second round had she not lost to Ekaterina Makarova, and former world number one Caroline Wozniacki have also questioned her presence at the tournament.
In addition to Stuttgart, Sharapova has been granted wildcards by the organisers of the events in Madrid and Rome.
She does not have a world ranking after her points expired during her suspension and would need to reach the final in Stuttgart to be eligible for French Open qualifying.
The Daily Telegraph report that Sharapova is likely to be given a wildcard into qualifying at Roland Garros rather than the tournament's main draw.
"She is starting at ground zero," Simon added.
"It is going to affect her seedings in big tournaments so she's still going to pay a penalty for a while.
"If you think about it from other leagues, most of them [bans] are half of a season or a full season. She's had a year and a half."
Former world number one Kim Clijsters echoed that view, saying that Sharapova "has done her time and her punishment".
"I was disappointed and surprised when the news came out but, having been on both sides of the spectrum as a tournament director and as a player, I don't think she needs to be punished more," the Belgian told BBC Sport.
World number five Simona Halep said: "I cannot support what the tournament director did, but also I cannot judge: it is his decision.
"In my opinion, for kids and young players, it's not OK to help with wildcards the players who were banned for doping."

Sharapova will need to set the alarm for her first day back at work. She has scheduled a 9.15 practice session on Centre Court: it will be the first time she has been allowed inside a tournament venue since her ban took effect.
Nine hours later, she will take on Roberta Vinci. The 34-year-old has lost six of her past seven matches, and taken just four games from Sharapova in the four sets they have played. This appears to be one of the best draws the five-time Grand Slam champion could have received.
It normally takes several months for players to return to their best after such a long break: concentration and decision-making often suffer. Sharapova will, though, be brimming with motivation as she has always maintained her error was purely an administrative one.

Output: Maria Sharapova's wildcard entry into the Stuttgart Open has been defended by WTA chief Steve Simon, who said it is in keeping with how former dopers are treated in other sports.


Input: Consider Input: The women officers' injuries are not life-threatening.
The assailant is said to have shouted "Allahu Akbar" ("God is greatest" in Arabic) during the assault outside the city's main police station.
Belgian Prime Minister Charles Michel told broadcaster RTL by phone: "Initial indications very clearly point towards terrorism."
Reports say the prime minister has cut short his holiday in the south of France and will return to Belgium for a meeting of the National Security Council on Sunday.
Charleroi was used as a base by some of the jihadists involved in the attacks on Paris in November 2015 and Brussels earlier this year.
Belgium has been on edge since suicide bombers attacked an airport terminal and a metro station in the Belgian capital on 22 March, killing 32 people and injuring many more.
The Belga news agency said one of the policewomen who was targeted suffered minor injuries, but the other had to receive treatment for serious wounds to her face.
Both were said to have been in a guard post set up to provide extra security for the police HQ.
Another officer, who was nearby, shot the attacker.


Output: A man shot by police after he attacked two officers with a machete in the Belgian city of Charleroi has died.
