An all-night gunbattle with Taliban insurgents who stormed a guesthouse in Kabul's diplomatic quarter ended at daybreak Wednesday, with four attackers killed in the second assault in two weeks on a venue popular with foreigners.

The raid on the property owned by a prominent political family triggered loud bursts of gunfire and explosions but the government reported no civilian or military casualties.

"Four attackers who had one RPG launcher, three AK-47s and one grenade launcher were killed in Wazir Akbar Khan," deputy interior minister Mohammad Ayoub Salangi said on Twitter.
The assault was claimed by the Taliban, who are intensifying their annual spring offensive despite repeated overtures from the government about reopening peace negotiations.

Police cordoned off the area after the raid began late Tuesday in the upmarket neighbourhood of Wazir Akbar Khan, home to several foreign embassies and diplomatic enclaves that are a prime target for attacks.

"The attackers who wanted to enter the guesthouse used grenades, but Afghan police used special tactics to kill them," Kabul's police chief Abdul Rahman Rahimi told reporters.

President Ashraf Ghani strongly condemned the attack, adding in a statement that "our security forces once again proved that they are capable of defending our country and people against any threats".
Fire trucks and police vehicles were seen around the guesthouse Wednesday morning, where broken shards of glass and bullet-riddled walls bore witness to the night's carnage.

Witnesses said the insurgents had seized a guard room near the front entrance but did not manage to progress further.

"The attackers took over a guard room at the gate and were throwing grenades toward the hotel and security forces around them," said Shafiqullah, a local resident.

The manager of the Heetal Hotel, owned by the family of Foreign Minister Salahuddin Rabbani and popular with foreigners, said all the guests were in safe rooms and no one was hurt.
"Heetal is very well fortified. After one or two initial explosions, our guards started firing on attackers who were unable to get inside," manager Beizhan told AFP by telephone from inside the guesthouse.

The Heetal was damaged in 2009 when a suicide bomber blew himself up outside the gate, killing eight people and wounding another 40.

- Heavy civilian toll -

The latest attack comes two weeks after 14 people -- mostly foreigners -- were killed in a Taliban attack on Kabul's Park Palace guesthouse that trapped dozens attending a concert.

The militants have launched a series of attacks in the capital and around the country as NATO forces have pulled back from frontlines.
The Taliban, who have been waging a 13-year war against the US-backed Afghan government, killed 26 Afghan police in multiple attacks in the volatile south a day earlier.

And a blast triggered by a Taliban car bomber ripped through the parking lot of the justice ministry in Kabul on May 19, killing four people and wounding dozens of others.

Official efforts to bring the Taliban to the negotiating table have so far borne little fruit.

The surge in attacks has taken a heavy toll on civilians, according to the United Nations Assistance Mission to Afghanistan. In the first four months of 2015, civilian casualties jumped 16 percent from the same period last year, it said.
Ghani's government has drawn criticism for failing to end growing insurgent attacks, which critics partly blame on political infighting and a lengthy delay in appointing a candidate for the crucial post of defence minister.

Ghani last Thursday nominated Mohammad Masoom Stanekzai, a top official in the government body overseeing the country's peace process, for the job.

The post had been left vacant for months due to disagreements between Ghani and his chief executive officer and former presidential election rival, Abdullah Abdullah.

Afghan forces are now solely responsible for security after NATO's combat mission formally ended in December, with a small follow-up force staying on to train and support local personnel.

Earlier this month NATO formally announced plans to retain a small military presence in Afghanistan after 2016 to help strengthen local security forces.
