EU set to widen sanctions on Russia over Ukraine
The European Union is set to agree new sanctions against Russia, targeting its finance, energy and defence sectors over the conflict in Ukraine.
Top Russian individuals and entities are already subject to EU sanctions for their alleged role in Ukraine's crisis.
Calls for the EU to act have been fuelled by the downing of flight MH17.
An international team has again failed to access the crash site in eastern Ukraine, amid heavy fighting between government forces and rebels there.
This is the third time in as many days that the team, which includes Dutch and Australian police officers, has had to abandon attempts to reach the site. Many of the 298 people travelling aboard Malaysia Airlines flight MH17 were Dutch or Australian.
Earlier on Tuesday, Dutch Prime Minister Mark Rutte asked Ukrainian President Petro Poroshenko to "halt hostilities" around the crash site, according to a spokesman for Mr Rutte, quoted by AFP news agency.
Ukraine's military has been on the offensive, seeking to encircle the pro-Russian separatist rebels in Donetsk region. In the latest developments:
- Several shells are said to have struck buildings in the separatist stronghold of Donetsk city
- Ukraine says its troops have entered the towns of Shakhtarsk and Torez in Donetsk region, and Lutuhyne in Luhansk region
- Ten Ukrainian soldiers and at least 22 civilians have reportedly been killed in the last 24 hours
- The dead civilians are said to include three children and five people at a home for the elderly
- A group of hackers sympathetic to the rebels says it has disabled the website of the Ukrainian president.

Europe's leaders did not want to move to economic sanctions but they were moved by two considerations: the outrage at the way investigators have been blocked from access to the crash site of the downed plane and, secondly, the fact that Russia, since the incident, has been allowing heavy weapons across the border into Ukraine.
The calculation in Europe is that it had to act for its own credibility and that it may have to go further to ensure that President Vladimir Putin and his inner circle understand that their actions carry consequences.
How will Russia respond? Hard to say, although Foreign Minister Sergei Lavrov said Russia would not retaliate or "fall into hysterics".
But - if all goes as expected - the EU will today take a significant step; that it has to risk some damage to its own economic interests in order to put pressure on President Putin and Russia.
EU ambassadors in Brussels are taking part in a meeting that is expected to lead to fresh sanctions. The meeting ends on Tuesday afternoon.
The fresh measures under discussion include restrictions on Russian banks accessing European markets, an arms embargo and curbs on dealings with the energy sector.
The leaders of France, Germany, Britain and the US already discussed possible sanctions in a conference call on Monday.
A spokeswoman for UK Prime Minister David Cameron later said that he and fellow European leaders had agreed to "impose further costs on Russia" for supporting the rebels in Ukraine.
Western nations have accused Russia of equipping the uprising in Ukraine with heavy weapons - including the missile that brought down flight MH17.
Russia has denied the charge. Russia and the rebels blame Ukrainian government forces for the attack on the airliner.
Any new EU sanctions could come into force within 24 hours of a deal being reached between the bloc's 28 member states.
Last weekend, the EU subjected a further 15 Russian individuals and 18 entities to asset freezes and visa bans for their alleged involvement in the Ukraine conflict.
The list of 87 targets of EU sanctions now includes the heads of the Federal Security Service (FSB) and foreign intelligence, the president of Chechnya, as well as two Crimean energy firms.
However, UK company BP, which owns nearly 20% of Russian state oil giant Rosneft, has warned that further sanctions against Russia could "adversely impact" its performance.
Meanwhile, Russia's foreign ministry has dismissed the latest UN human rights report on the Ukraine conflict as "unobjective and even hypocritical".
The UN's human rights chief warned on Monday that the downing of MH17 may be a "war crime".
According to the UN, at least 1,129 people have been killed and 3,442 wounded in the fighting in Ukraine since mid-April. The violence has displaced more than 200,000 people, many of them fleeing to neighbouring Russia.
